“I can alter my life by altering my attitude. He who would have nothing to do with thorns must never attempt to gather flowers.”
― Henry David Thoreau

“In the morning I bathe my intellect in the stupendous and cosmogonal philosophy of the Bhagvat Geeta, since whose composition years of the gods have elapsed, and in comparison with which our modern world and its literature seem puny and trivial; and I doubt if that philosophy is not to be referred to a previous state of existence, so remote is its sublimity from our conceptions. I lay down the book and go to my well for water, and lo! there I meet the servant of the Bramin, priest of Brahma and Vishnu and Indra, who still sits in his temple on the Ganges reading the Vedas, or dwells at the root of a tree with his crust and water jug. I meet his servant come to draw water for his master, and our buckets as it were grate together in the same well. The pure Walden water is mingled with the sacred water of the Ganges.”
― Henry David Thoreau, Walden or, Life in the Woods

“It is a curious situation that the sea, from which life first arose should now be threatened by the activities of one form of that life. But the sea, though changed in a sinister way, will continue to exist; the threat is rather to life itself.”
― Rachel Carson, The Sea Around Us

“A man is rich in proportion to the number of things which he can afford to let alone.”
― Henry David Thoreau, Walden or, Life in the Woods
