"I am the original fragrance of the earth, and I am the heat in fire. I am the life of all that lives, and I am the penances of all ascetics." – Bhagavad Gita As It Is - A.C Bhaktivedanta Swami Prabhupada, spiritual master 07.09
All Varieties of fragrance come from the earth. The gardener uses the same fertilizer and same water but different flowers have different fragrances. How is this done? Can any scientist answer? Why are there differences? If it is nature and the ingredients are the same, why is nature not producing the same kind of flower or tree or fruit?
Bhagavad-gita says that nature is not all in all. Nature, the material elements, cannot work independently. There is superintendence by the Supreme Personality of Godhead God. He dictates "This seed will produce this flower and this fregrance." We fools cannot explain the variety. We say nature but What is nature? There must be a brain behind nature. Otherwise, how does a rose come out so nicely? Even from the artistic point of view, if you want to paint a flower you have to take so much labor. You have to use instruments and mix color and even then the flower you paint is not as good as the original flower.
So if you have to apply so much brainpower to paint a third-class flower, how can the first class flower have no brain behind it? is that very good logic? There must be a brain. And that is stated here: “It is under My superintendence.”
God is giving us intelligence: “If you do not go to the temple or do not hear from the spiritual master, you can at least try to understand My presence when you see or smell a flower.” Is that very difficult? God consciousness is so nice that you can be God conscious even by drinking water, even by seeing the sunshine, even by seeing the moonshine. Or if you are a Vedic scholar, by chanting om or even by hearing the sound vibration. Or by seeing a flower or smelling a flower. Or by seeing something brilliant.
