Paramahamsa Vijnana Yoga-Bhagavad Gita Chapter 7 [Knowledge of the Ultimate Truth]
Krishna Said > Shaloka: 9
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.
Punya means that which is not decomposed; punya is original. Everything in the material world has a certain flavor or fragrance, as the flavor and fragrance in a flower, or in the earth, in water, in fire, in air, etc. The uncontaminated flavor, the original flavor, which permeates everything, is Krishna. Similarly, everything has a particular original taste, and this taste can be changed by the mixture of chemicals. So everything original has some smell, some fragrance, and some taste. Vibhava means fire. Without fire we cannot run factories, we cannot cook, etc., and that fire is Krishna. The heat in the fire is Krishna. According to Vedic medicine, indigestion is due to a low temperature in the belly. So even for digestion fire is needed. In Krishna consciousness we become aware that earth, water, fire, air and every active principle, all chemicals and all material elements are due to Krishna. The duration of man’s life is also due to Krishna. Therefore by the grace of Krishna, man can prolong his life or diminish it. So Krishna consciousness is active in every sphere.
