1 " Yoga is an exact science in the form of poetry when we measure the flow of neurotransmitters in the brain. "

2 " Depression, we are told over and over again, is a brain disease, a chemical imbalance that can be adjusted by antidepressant medication. In an informational brochure issued to inform the public about depression, the US National Institute for Mental Health tells people that 'depressive illnesses are disorders of the brain' and adds that 'important neurotransmitters - chemicals that brain cells use to communicate - appear to be out of balance'. This view is so widespread that it was even proffered by the editors of PLoS [Public Library of Science] Medicine in their summary that accompanied our article. 'Depression,' they wrote, 'is a serious medical illness caused by imbalances in the brain chemicals that regulate mood', and they went on to say that antidepressants are supposed to work by correcting these imbalances.The editors wrote their comment on chemical imbalances as if it were an established fact, and this is also how it is presented by drug companies. Actually, it is not. Instead, even its proponents have to admit that it is a controversial hypothesis that has not yet been proven. Not only is the chemical-imbalance hypothesis unproven, but I will argue that it is about as close as a theory gets in science to being dis-proven by the evidence. "

3 " No drugs here, no manipulation of neurotransmitters that leaves our worldly problems unattended. And no talking cures because explicit insight is not needed. All that is required is courage: the courage to encounter discomfort and stay with it long enough to be changed by it, strengthened. "

4 " Yatima found verself gazing at a red-tinged cluster of pulsing organic parts, a translucent confusion of fluids and tissue. Sections divided, dissolved, reorganised. It looked like a flesher embryo – though not quite a realist portrait. The imaging technique kept changing, revealing different structures: Yatima saw hints of delicate limbs and organs caught in slices of transmitted dark; a stark silhouette of bones in an X-ray flash; the finely branched network of the nervous system bursting into view as a filigreed shadow, shrinking from myelin to lipids to a scatter of vesicled neurotransmitters against a radio-frequency MRI chirp. There were two bodies now. Twins? One was larger, though – sometimes much larger. The two kept changing places, twisting around each other, shrinking or growing in stroboscopic leaps while the wavelengths of the image stuttered across the spectrum.One flesher child was turning into a creature of glass, nerves and blood vessels vitrifying into optical fibres. A sudden, startling white-light image showed living, breathing Siamese twins, impossibly transected to expose raw pink and grey muscles working side by side with shape-memory alloys and piezoelectric actuators, flesher and gleisner anatomies interpenetrating. The scene spun and morphed into a lone robot child in a flesher's womb; spun again to show a luminous map of a citizen's mind embedded in the same woman's brain; zoomed out to place her, curled, in a cocoon of optical and electronic cables. Then a swarm of nanomachines burst through her skin, and everything scattered into a cloud of grey dust.Two flesher children walked side by side, hand in hand. Or father and son, gleisner and flesher, citizen and gleisner... Yatima gave up trying to pin them down, and let the impressions flow through ver. The figures strode calmly along a city's main street, while towers rose and crumbled around them, jungle and desert advanced and retreated.The artwork, unbidden, sent Yatima's viewpoint wheeling around the figures. Ve saw them exchanging glances, touches, kisses – and blows, awkwardly, their right arms fused at the wrists. Making peace and melting together. The smaller lifting the larger on to vis shoulders – then the passenger's height flowing down to the bearer like an hourglass's sand. "

5 " God is created by the brain and can also be destroyed by the brain. But this way ‘Love’ doesn’t exist either, because it also is the result of molecular interaction within the brain. Love is a result of complex and mind-blowing interactions between neurotransmitters like Oxytocin, Dopamine, Serotonin, Endorphins and the reward center of the brain. Does this mean we should downright stop loving our family or friends? Since there is no existence of actual ‘Love’, should we just deny what our heart feels for our beloved ones? Whatever the answer is, the same goes for the faith upon divine existence. Only one thing to remember – Love gives life, so should faith. "

6 " In a very real way, attention is a drug. Like dope, attention makes people feel good by delivering a ‘’hit’’ of certain neurotransmitters (chemicals that transmit, or block the transmission of electrochemical currents) in the brain. Like anything that does this (viz., sex, risk-taking, power), in excessive amounts it’s addictive. And, simply because it works, nothing is as addictive as a pain killer. Hence Narcissus is well-named from the Greek word for narcosis.Attention is his pain killer. "
