BG 7.8: I am the taste in water, O son of Kunti, and the radiance of the sun and the moon. I am the sacred syllable Om in the Vedic mantras; I am the sound in ether, and the ability in humans.


Having said that he is the origin and the basis of all that exists, Shree Krishna now explains the truth of his statement in these four verses. When we eat fruits, the sweetness in the taste indicates the presence of sugar in them. Similarly, Shree Krishna reveals his presence in all the modifications of his energies. Thus, he says that in water he is the taste, which is its unique intrinsic property. After all, who can separate the taste of water from water? All other forms of the material energy—gases, fires, solids—need liquids to carry their taste. Try putting a solid on your dry tongue, and you will not taste anything. But when solids are dissolved by the saliva in the mouth, then their taste is perceived by the taste buds on the tongue.

Similarly, ākāśha (space) functions as the vehicle for sound. Sound modifies itself into various languages, and Shree Krishna explains that he is the basis of it all, because the sound in space is his energy. Further, he says that he is the syllable “Om,” which is an important element of Vedic mantras. He is also the energy source of all the abilities manifest in humans.
