Lecture on Bhagavad-gita Chapter 14, Text 4 titled “Everything Perfectly Made by Nothing.” (evolution)
It should be understood that all species of life, O son of Kunti, are made possible by birth in this material nature, and that I am the seed-giving father.
In this verse it is clearly explained that the Supreme Personality of Godhead, Krishna, is the original father of all living entities. The living entities are combinations of the material nature and the spiritual nature. Such living entities are seen not only on this planet but on every planet, even on the highest, whereBrahma is situated. Everywhere there are living entities; within the earth there are living entities, even within water and within fire. All these appearances are due to the mother, material nature, and Krishna‘s seed-giving process. The purport is that the material world is impregnated with living entities, who come out in various forms at the time of creation according to their past deeds.
