“To draw an analogy: a man's suffering is similar to the behavior of a gas. If a certain quantity of gas is pumped into an empty chamber, it will fill the chamber completely and evenly, no matter how big the chamber. Thus suffering completely fills the human soul and conscious mind, no matter whether the suffering is great or little. Therefore the "size" of human suffering is absolutely relative.”

“Every human being relies on and is bounded by his knowledge and experience to live. This is what we call “reality”. However, knowledge and experience are ambiguous, thus reality can become illusion. Is it not possible to think that, all human beings are living in their assumptions?”

“It is still a fairly astounding notion to consider that atoms are mostly empty space, and that the solidity we experience all around us is an illusion. When two objects come together in the real world – billiard balls are most often used for illustration – they don’t actually strike each other. ‘Rather,’ as Timothy Ferris explains, ‘the negatively charged fields of the two balls repel each other … [W]ere it not for their electrical charges they could, like galaxies, pass right through each other unscathed26.’ When you sit in a chair, you are not actually sitting there, but levitating above it at a height of one angstrom (a hundred millionth of a centimetre), your electrons and its electrons implacably opposed to any closer intimacy.”

“Nature may reach the same result in many ways. Like a wave in the physical world, in the infinite ocean of the medium which pervades all, so in the world of organisms, in life, an impulse started proceeds onward, at times, may be, with the speed of light, at times, again, so slowly that for ages and ages it seems to stay, passing through processes of a complexity inconceivable to men, but in all its forms, in all its stages, its energy ever and ever integrally present. A single ray of light from a distant star falling upon the eye of a tyrant in bygone times may have altered the course of his life, may have changed the destiny of nations, may have transformed the surface of the globe, so intricate, so inconceivably complex are the processes in Nature. In no way can we get such an overwhelming idea of the grandeur of Nature than when we consider, that in accordance with the law of the conservation of energy, throughout the Infinite, the forces are in a perfect balance, and hence the energy of a single thought may determine the motion of a universe.”
