Sankarsana is the original source of all living entities because they are all expansions of His marginal potency. Some of them are conditioned by material nature, whereas others are under the protection of the spiritual nature. The material nature is a conditional manifestation of spiritual nature, just as smoke is a conditional stage of fire. Smoke is dependent on fire, but in a blazing fire there is no place for smoke. Smoke disturbs, but fire serves. The serving spirit of the residents of the transcendental world is displayed in five varieties of relationship with the Supreme Lord, who is the central enjoyer. In the material world everyone is a self-centered enjoyer of mundane happiness and distress. A person considers himself the lord of everything and tries to enjoy the illusory energy, but he is not successful because he is not independent: he is but a minute particle of the energy of Lord Sankarsana. All living beings exist under the control of the Supreme Lord, who is therefore called Narayana.
