Ideologies get corrupt in time, because humans following those ideologies cannot help but foster an implicit, i.e. subconscious hatred towards other humans following different ideologies.

I do not see emotions and feelings as the intangible and vaporous qualities that many presume them to be. Their subject matter is concrete, and they can be related to specific systems in body and brain, no less so than vision or speech.

[I]f you can be with the pleasant without chasing after it, with the unpleasant without resisting it, and with the neutral without ignoring it - [...] that is an incredible [...] freedom.

If you could have sufficient insight into all the inner and outer parts of your mental life, along with remembrance and intelligence enough to consider all the circumstances and take them into account, you would be a true prophet and visualize the future in the present as in a mirror.

I (God) am only a part of your own human consciousness, but a really bizarre part.

I have been at war with parts of myself for so long

- I'm a Neuroscientist. - What's that? What do you study? - I study your brain!

Individuals who rate high on the so-called Anxiety Sensitivity Index, or ASI, have a high degree of what's known as interoceptive awareness, meaning they are highly attuned to the inner workings on their bodies, to the beepings and bleatings, the blips and burps, of their physiologies; they are more conscious of their heart rate, blood pressure, digestive burblings, and so forth than other people are.

Infinite and finite are both mental constructs.

In the society of thinking humanity, the natural law of trust should be - In I, I trust.

In this universe, all we perceive is a virtual reality created by the neurons.

In your daily life, you make dozens of chooses between an alternative with higher overall value and a more tempting but ultimately inferior option.

I don't trust anybody who isn't a little bit neurotic

If I ask you, are you conscious right now? You'd go right ahead and tell me - yes. That's because your conscious mind is constructing an awareness in you about everything around you. And underneath that operation of your conscious mind, there are billions of neurons working in proper harmony.

If you believe you can change—if you make it a habit—the change becomes real. This is the real power of habit: the insight that your habits are what you choose them to be. Once that choice occurs—and becomes automatic—it’s not only real, it starts to seem inevitable.

Imagine for a moment that we are nothing but the product of billions of years of molecules coming together and ratcheting up through natural selection, that we are composed only of highways of fluids and chemicals sliding along roadways within billions of dancing cells, that trillions of synaptic conversations hum in parallel, that this vast egglike fabric of micron-thin circuitry runs algorithms undreamt of in modern science, and that these neural programs give rise to our decision making, loves, desires, fears, and aspirations. To me, that understanding would be a numinous experience, better than anything ever proposed in anyone's holy text.

Imagine yourself having a fight with your romantic partner. The tension of the situation makes your limbic system run at full throttle and you become flooded with stress hormones like cortisol and adrenalin. The high levels of these chemicals suddenly make you so damn angry, that you burst out in front of your partner saying, “I wish you die, so that I can have some peace in my life”. Given the stress of the situation through highly active limbic system, your PFC loses its freedom to take the right decision and you burst out with foul language in front of your partner, that may ruin your relationship. In simple terms due to your mental instability, you lost your free will to make the right decision. But when the conversation is over, and you relax for a while, your stress hormone levels come down to normal, and you regain your usual cheerful state of mind. Immediately, your PFC starts analyzing the explosive conversation you had with your partner. Healthy activity of the entire frontal lobes, especially the PFC suddenly overwhelms you with a feeling of guilt. Your brain makes you realize, that you have done something devilish. As a result, now you find yourself making the willful decision of apologizing to your partner and making up to him or her, no matter how much effort it takes, because your PFC comes up the solution that it is the healthiest thing to do for your personal life. From this you can see, that what you call free will is something that is not consistent. It changes based on your mental health. Mental instability or illness, truly cripples your free will. And the healthier your frontal lobes are, the better you can take good decisions. And the most effective way to keep your frontal lobes healthy is to practice some kind of meditation.

In every walk of life, you do have the freedom to choose, but that freedom is based on the perception of the world and yourself which you have gained until that moment of life.

in simple terms, what you perceive as real, is actually a neurological reconstruction or simulation of the actual real thing. It’s not as simple as saying, we see as it is. Actually we do not ever see as it is.

I take it as a compliment when somebody calls me crazy. I would be offended if I was one of the sheeple, one of the sleepwalkers in the matrix or part of the collective hallucination we call 'normal

It is better to be foolish than a dilettante.

It is difficult to overstate the importance of understanding mirror neurons and their function. They may well be central to social learning, imitation, and the cultural transmission of skills and attitudes—perhaps even of the pressed-together sound clusters we call words. By hyperdeveloping the mirror-neuron system, evolution in effect turned culture into the new genome. Armed with culture, humans could adapt to hostile new environments and figure out how to exploit formerly inaccessible or poisonous food sources in just one or two generations—instead of the hundreds or thousands of generations such adaptations would have taken to accomplish through genetic evolution. Thus culture became a significant new source of evolutionary pressure, which helped select brains that had even better mirror-neuron systems and the imitative learning associated with them. The result was one of the many self-amplifying snowball effects that culminated in Homo sapiens, the ape that looked into its own mind and saw the whole cosmos reflected inside.

It is important to note that the design of an entire brain region is simpler than the design of a single neuron. As discussed earlier, models often get simpler at a higher level—consider an analogy with a computer. We do need to understand the detailed physics ofsemiconductors to model a transistor, and the equations underlying a single real transistor are complex. A digital circuit that multiples two numbers requires hundreds of them. Yet we can model this multiplication circuit very simply with one or two formulas. An entire computer with billions of transistors can be modeled through its instruction set and register description, which can be described on a handful of written pages of text and formulas. The software programs for an operating system, language compilers, and assemblers are reasonably complex, but modeling a particular program—for example, a speech recognition programbased on hierarchical hidden Markov modeling—may likewise be described in only a few pages of equations. Nowhere in such a description would be found the details ofsemiconductor physics or even of computer architecture. A similar observation holds true for the brain. A particular neocortical pattern recognizer that detects a particular invariant visualfeature (such as a face) or that performs a bandpass filtering (restricting input to a specific frequency range) on sound or that evaluates the temporal proximity of two events can be described with far fewer specific details than the actual physics and chemicalrelations controlling the neurotransmitters, ion channels, and other synaptic and dendritic variables involved in the neural processes. Although all of this complexity needs to be carefully considered before advancing to the next higher conceptual level, much of it can be simplified as the operating principles of the brain are revealed.

It is in the nature of the human mind to give in, and hold on, to the source of solace with all the might it can muster. Life is hard and any figure that tends to ease the subjective perception of that hardship, attains a high pedestal of utmost reverence in the realm of the individual mind. It all takes place at a molecular level in the human brain with the purpose of self-preservation.

It is much easier to concentrate the mind on external things, than to concentrate on the mind itself. For example, a Neuroscientist can be the smartest man (or woman) on earth in his understanding of the human mind. He may know all the neurochemical changes underlying an outrageous behavior of a person. But when he gets mad himself, very little of his own scientific intellect would actually come in handy for him to control his rage. The virtue of self-control is a skill, which requires practice, regardless of all the neurobiological expertise in the world.

It is necessary for the future scientists interested in the field of Neurotheology, to have a bit naïve approach towards the whole idea of God and religion beyond the conventional labels of religion and atheism.

It is pretty simple - mind is a part of life - consciousness is a part of mind - God is a part of consciousness.

It is the finding of neuroscience, in fact, that belief is at least in part a matter of emotion. Whatever we believe to be true lights up areas of our brain responsible for self-identification and the processing of feelings and sentiments. If we believe something, then, the object of our belief becomes an emotionally potent aspect of our own self-image. There is some common sense to this, too: the most passionate of believers and the most strident of New Atheists are palpably, visibly fired up and ready to defend their positions.

It may seem demeaning to the vanity of some individuals, but like all elements of the mind, God and all its correlated sensations of divinity are the majestic creations of neurobiology.

It might weigh little over a kilogram but, taken on its own scale, the brain is unimaginably vast. One cubic millimetre contains between twenty and twenty-five thousand neurons. It has eighty-six billion of these cells, and each one is complex as a city and is in contact with ten thousand other neurons just like it. Within just one cubic centimetre of brain tissue, there is the same number of connections as there are stars in the Milky Way. Your brain contains a hundred trillion of them. Information in the form of electricity and chemicals flows around these paths in great forking trails and in circuits and feedback loops and fantastical storms of activity tat bloom to life speeds of up to a hundred and twenty metres per second. According to the neuroscientist V. S. Ramachandran, 'The number of permutations and combinations of activity that are theoretically possible exceeds the number of elementary particles in the universe.' And yet, he continues, 'We know so little about it that even a child's questions should be seriously entertained.

It's been long since thinking humanity has learnt that love is a majestic creation of the brain, yet that knowledge hasn't made love be deemed any less glorious. Then why should it threaten the religious believer to learn that divinity as well is a natural creation of the brain?

It's okay to not be okay - it means that your mind is trying to heal itself.

It's simply not the case that people use one particular lobe, or a circumscribed area of the brain, to read a novel, or write an essay, or solve an equation, or calculate the angle of a triangle. And, unfortunately, neuroscience has yet to reach the stage at which it can peer into the brain and determine capacity for solving simultaneous equations or readiness to learn calculus.

It was grace. In those who were always honest, the dlPFC, vlPFC, and ACC were in veritable comas when the chance to cheat arose. There's no conflict. There's no working hard to do the right thing. You simply don't cheat.

​I wanted to present Neuroscience to people in a way that would diminish their differences.

I was not born with a silver spoon in my mouth, nor did I have access to information like you do today via the internet. I had to learn everything the hard way. And I had to become a scientist the old-fashioned way, which is, not through academia, but through trial and error. And my hardship opened up unforeseen gateways of perception in my mind. And through these gateways, today the whole world is able to see its inner self.

Live with technology, not through technology.

Losing connection with our loved one jeopardizes our sense of security. The alarm goes off in the brain’s amygdala, or Fear Central, as neuroscientist Joseph LeDoux of the Center for Neural Science at New York University has dubbed it. This almond-shaped area in the midbrain triggers an automatic response. We don’t think; we feel, we act.

Masturbating is no more sinful than praying or meditating.

Masturbation and meditation both promote physical and mental wellbeing.

Meditation is good for the elderly, great for adults, even greater for children, and greater still for pregnant women. So, meditate and be well.

Maybe the human brain is an object beyond the reach of metaphor, for the simple reason that it is the only object capable of creating metaphors to describe itself. There really is nothing else like it. The human brain creates the human mind, and then the human mind tries to underhand the human brain, however long it takes and whatever the cost.

Meditation has also been proven scientifically to untangle and rewire the neurological pathways in the brain that make up the conditioned personality. Buddhist monks, for example, have had their brains scanned by scientists as they sat still in deep altered states of consciousness invoked by transcendental meditation and the scientists were amazed at what they beheld. The frontal lobes of the monks lit up as bright as the sun! They were in states of peace and happiness the scientists had never seen before. Meditation invokes that which is known in neuroscience as neuroplasticity; which is the loosening of the old nerve cells or hardwiring in the brain, to make space for the new to emerge. Meditation, in this sense, is a fire that burns away the old or conditioned self, in the Bhagavad Gita, this is known as the Yajna; “All karma or effects of actions are completely burned away from the liberated being who, free from attachment, with his physical mind enveloped in wisdom (the higher self), performs the true spiritual fire rite.

Memorizing facts and then regurgitating them into carefully crafted words is not science people. It’s intellectual bulimia. Real science happens when we explore what we don’t know. The first law of understanding the human brain and the mind within, is to be an explorer.

Memory is the binding foam of our mental life.

Memory is the coherence of life, that possesses all your emotions, and ambitions. Without it, your joyous as well as agonizing experiences of life won’t have any significance to you whatsoever.

Modern society is modern because of its mental cocktail of reasoning and compassion. Turn the compassion network in the brain off, and it will be a society of heartless robots. On the other hand, turn the reasoning network off, and it will be a society of dumb sentimental apes.

Morality does not come from a book, it comes from the human mind.

Morality does not come to this mortal world from some imaginary paradise. It rises from the neurons of mortal humans.

More and more people will start telling themselves: "I don't understand what all these neuroexperts and consciousness philosophers are talking about, but the upshot seems pretty clear to me. The cat is out of the bag: We are gene-copying bio-robots, living out here on a lonely planet in a cold and empty physical universe. We have brains but no immortal souls, and after seventy years or so the curtain drops. There will never be an afterlife, or any kind of reward or punishment for anyone, and ultimately everyone is alone. I get the message, and you had better believe I will adjust my behavior to it. It would probably be smart not to let anybody know I've seen through the game. The most efficient strategy will be to go on pretending I'm a conservative, old-fashioned believer in moral values.
