I worship the Supreme Personality of Godhead, Govinda [Krsna], who is the original personabsolute, infallible, without beginning, although expanded into unlimited forms, still the same original, the oldest, and the person always appearing as a fresh youth. Such eternal, blissful, all-knowing forms of the Lord cannot be understood even by the best Vedic scholars, but they are always manifest to pure, unalloyed devotees. The Supreme Personality of Godhead has no cause, for He is the cause of everything. The Lord is beyond the workings of cause and effect. He is eternally existing. In another verse the Brahma-samhita says, andantara-stha-paramanu-cayantara-stham: the Lord exists within the gigantic universe and within the atom. The descent of the Lord into the atom and the universe indicates that without His presence, nothing could factually exist. Scientists say that water is a combination of hydrogen and oxygen, but when they see a vast ocean they are puzzled about where such a quantity of hydrogen and oxygen could have come from. They think that everything evolved from chemicals, but where did the chemicals come from? That they do not know. Since the Supreme Personality of Godhead is the cause of all causes, He can produce immense quantities of chemicals to create a situation for chemical evolution. We actually see that chemicals are produced from living entities. For example, a lemon tree produces many tons of citric acid. The citric acid is not the cause of the tree; rather, the tree is the cause of the acid. Similarly, the Supreme Personality of Godhead is the cause of everything. He is the cause of the tree that produces the citric acid (bijam mam sarva-bhutanam). Devotees can see that the original potencies causing the cosmic manifestation are not in chemicals but in the Supreme Personality of Godhead, for He is the cause of the chemicals.
