BG 15.13: Permeating the earth, I nourish all living beings with My energy. Becoming the moon, I nourish all plants with the juice of life.


The word gām means earth and the word ojasā means energy.  The earth is a mass of matter, but by the power of God, it is made inhabitable and it sustains various species of movable and non-movable living beings.  For example, from childhood we wondered why the ocean water is salty.  The fact is that if it were not salty, it would have bred disease in abundance and become uninhabitable.  So, whatever the physical phenomena associated with it, ocean water is salty by the will of God.  George Wald, a Nobel Prize winning scientist states in his book, A Universe that Breeds Life:  “If any one of the considerable number of the physical properties of our universe were other than they are, then life, that now appears to be so prevalent, would be impossible, here or anywhere.”  From Shree Krishna’s statement, we understand that it is God’s energy which has brought about the appropriate physical properties for life to exist on the planet earth.  

Further, the moonlight, which has the quality of ambrosial nectar, nourishes all plant life, such as herbs, vegetables, fruits, and grains.  Shree Krishna states that it is He who imparts this nourishing characteristic to the moonlight.
