“The Upanishadic verse runs as follows: nityo nityanam chetanash chetananam. The purport is that amongst all the living entities, both conditioned and liberated, there is one supreme living personality, the Supreme Personality of Godhead, who maintains them and gives them all the facility of enjoyment according to different work.” (Shrila Prabhupada, Bhagavad-gita, 15.17 Purport)
