“Discipline is important, we need to be more focused on what we put into our bodies.”

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.

Context: Please don't say lightly that these are just religious concepts and not practical. These are laws governing human conduct, which apply as rigidly as the law of gravity. When we disregard these laws in any walk of life, chaos results. Through obedience to these laws this world of ours will enter a period of peace and richness of life beyond our fondest dreams.
The key word for our time is practice. We have all the light we need, we just need to put it into practice.
