“The Sun, with all the planets revolving around it, and depending on it, can still ripen a bunch of grapes as though it had nothing else in the Universe to do.”

                  ―Galileo Galilei

“Love takes off the masks that we fear we cannot live without and know we cannot live within. I use the word 'love' here not merely in the personal sense but as a state of being, or a state of grace - not in the infantile American sense of being made happy but in the tough and universal sense of quest and daring and growth.”

                       ― James Baldwin, The Fire Next Time

The more powerful you are, the easier it is to tell other people what to do, and the harder it is to know who you are.  Thus the royal "We."

"I think Nature’s imagination is so much greater than man’s.  She’s never going to let us relax."

                         —Richard Feynman

"It is important that students bring a certain ragamuffin, barefoot irreverence to their studies; they are not here to worship what is known, but to question it. " 

                       — Jacob Bronowski (The Ascent of Man)

"Whoever would study medicine aright must learn of the following subjects.

First he must consider the effects of each of the seasons of the year and the differences between them.

Secondly he must study the warm and the cold winds, both those which are common to every country and those peculiar to a particular locality.

Lastly the effect of water on the health must not be forgotten. "

                              —On Air, Water and Places, by Hippocrates

"Can we move nations and people in the direction of sustainability?  Such a move would be a modification of society comparable in scale to only two other changes:  the Agricultural Revolution of the late Neolithic and the Industrial Revolution of the past two centuries.  Those revolutions were gradual, spontaneous, and largely unconscious.  This one will have to be a fully conscious operation, guided by the best foresight that science can provide....If we actually do it, the undertaking will be absolutely unique in humanity's stay on the Earth."

                                 —William D. Ruckelshaus, 1989

“The mind is subtle, its creativity is absolute, its power is infinity...Whenever the mind is tuned into passion, and not consciousness, the net result will be desire. But once you become conscious, you will have one desire only: to be noble.”

“Now what is intelligence? It is when your senses and your consciousness calculate on the spot. Senses will say one thing. Consciousness will say something different. And when you can put it together, two and two, that is intelligence.”

“When your mind thinks too much, it loses touch with the reality of life. To be real, our feet should be on the Earth and our head should be in the Heavens.”

“The soul is the highest self, body and mind are there to serve the soul. But when the two servants start serving each other, the Master goes hungry. That is why souls are hungry, empty and in pain. The soul can only find liberation if the mind and body serve it.”

“Everyone, whether a king or queen, pauper or beggar, lover or deserter, attorney or accused, is going to be challenged in life. One thing you cannot escape is challenge. Whether you challenge the challenge or you give in to the challenge, that is what decides your spirituality. Is your spirit higher than the challenge so you can face it? ”
