Srimad Bhagavasgeeta :
Chapter-7. ( Jnana-Vijnana-Yogam )
Slokam-9. ( I am the original/pure 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.)
punyo gandhah prthivyam ca tejascasmi vibhavasau,
jivanam sarva-bhuteshu tapascasmi tapasvishu.
prthivyam punyah gandhah ca = the pure fragrance in the earth also;
vibhavasau tejah ca = the brightness /heat of the fire also;
sarva-bhuteshu jivanam = the chaithanyam in all living entities;
tapasvishu tapah ca asmi = and also the tapas of those practicing ....I am.
Lord Krishna is stating that He is the subtle principle of fragrance innate within the Earth. The particle ca meaning and includes after smell the other four subtle principles such as taste, touch, sight and sound. He is the pure brilliance in fire. He is the vital life force in all sentient beings and He is the potency of austerities in the ascetics and forest dwellers giving them the power to endure in their penance to overcome the dualities such as cold and heat.
Continuing further Lord Krishna describes how He is the essence of smell as the pure unadulterated odour which exists as the substratum of the Earth. It can also be interpreted that since the manifestations of the Supreme Lord as the substratum of everything has been confirmed and as only the sweet pure odour of the Earth in all its excellence can only emanate from Him it is being inculcated in these
Lord Krishna is the bright natural glow found in fire. He is the vital force of vitality which sustains and all life and animates all beings and He is tapas or austerities found in the yogis or one perfecting the science of the individual consciousness attaining communion with the ultimate consciouness, the ascetics, the hermits and the celibate monks; by which they have the capacity to withstand dualities such as heat and cold or pleasure and pain.
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 Lord. The heat in the fire is Lord. According to Vedic medicine, indigestion is due to a low temperature in the belly. So even for digestion fire is needed. In the consciousness we become aware that earth, water, fire, air and every active principle, all chemicals and all material elements are due to Lord. The duration of man's life is also due to Him. Therefore by the grace of Lord, man can prolong his life or diminish it. So consciousness is active in every sphere.
