“All our power lies in both mind and body; we employ the mind to rule, the body rather to serve; the one we have in common with the Gods, the other with the brutes.”

All and Everything: Views from the Real World (1973)
Context: The power of changing oneself lies not in the mind, but in the body and the feelings. Unfortunately, however, our body and our feelings are so constituted that they don’t care a jot about anything so long as they are happy. They live for the moment and their memory is short. The mind alone lives for tomorrow. Each has its own merits. The merit of the mind is that it looks ahead. But it is only the other two that can "do."

The Yoga Sutras of Patanjali, Book II, 2008
Context: The ego rules the mind because it links the “I” with the mind and body. If the “I,” which is another name for the self, were not identified with the mind and body, the ego would have no power. Self-study [svadhyaya], therefore, is the set of practices that investigates the nature of the self to discover its origin. When the origin is found to be separate from the body, the ego loses the battle and peace is attain. (Bk. II, Sutra 1, p.5)

The Sun My Heart (1996)
Context: We have to remember that our body is not limited to what lies within the boundary of our skin. Our body is much more immense. We know that if our heart stops beating, the flow of our life will stop, but we do not take the time to notice the many things outside of our bodies that are equally essential for our survival. If the ozone layer around our Earth were to disappear for even an instant, we would die. If the sun were to stop shining, the flow of our life would stop. The sun is our second heart, our heart outside of our body. It gives all life on Earth the warmth necessary for existence. Plants live thanks to the sun. Their leaves absorb the sun's energy, along with carbon dioxide from the air, to produce food for the tree, the flower, the plankton. And thanks to plants, we and other animals can live. All of us—people, animals, plants, and minerals—"consume" the sun, directly and indirectly. We cannot begin to describe all the effects of the sun, that great heart outside of our body.
When we look at green vegetables, we should know that it is the sun that is green and not just the vegetables. The green color in the leaves of the vegetables is due to the presence of the sun. Without the sun, no living being could survive. Without sun, water, air, and soil, there would be no vegetables. The vegetables are the coming-together of many conditions near and far.
