Krishna also explains how the life-promoting functions of Nature are equally the Soul’s own:

Permeating earth, the Supreme alone sustains beings with its splendour. Becoming the lunar lustre, It preserves the sapidity of all herbs and vegetables.

Of the countless planets and heavenly bodies, the earth hosts our life, movement and varied activities. How many forms of life are there on earth! To enable all these to sustain their life, what an enormous variety of food and nourishment is available! How many seeds, minerals and salts, water, countless physical, chemical and biological processes and transmutations are there! Myriad are the contents and characteristics the earth possesses to bring about, promote and sustain life. Krishna says that all these emerge from the same spiritual Soul. Though there is surprising plurality in manifestation, in causality it is the singular Soul.

Sun is hot, whereas the moon is cool. In the growth, flowering and fruition of plants and vegetables, moon has a distinct role to play. Krishna describes the moon as rasātmakaḥ. Moon holds the power to instill sapidity into the seeds, sprouts, plants and creepers thereby making them healthy and vibrant. There are flowers that blossom with the touch of the cool beams of the moon.

Earlier, he has linked yajña with rainfall that results in production of food grains, which alone provides sustenance for living beings. Here he goes a step further to say that like the hot sun the cool moon also has a close link with the health and resourcefulness of the plant kingdom. It is a traditional practice among farmers to expose seeds to moonlight for a few days. By this, the seeds are expected to imbibe some special vigour to germinate healthily. Does this not give a clue for further scientific investigation?
