Śrī Caitanya-caritāmṛta - Madhya-līlā 20.108-110

"“It is the living entity’s constitutional position to be an eternal servant of Kṛṣṇa because he is the marginal energy of Kṛṣṇa and a manifestation simultaneously one with and different from the Lord, like a molecular particle of sunshine or fire. Kṛṣṇa has three varieties of energy."

"“ ‘Just as the illumination of a fire, which is situated in one place, is spread all over, the energies of the Supreme Personality of Godhead, Parabrahman, are spread all over this universe.’"
