Lord Brahmā said: I, Lord Śiva, all of you demigods, the demons, the living entities born of perspiration, the living beings born of eggs, the trees and plants sprouting from the earth, and the living entities born from embryos — all come from the Supreme Lord, from His incarnation of rajo-guṇa [Lord Brahmā, the guṇa-avatāra] and from the great sages [ṛṣis] who are part of me. Let us therefore go to the Supreme Lord and take shelter of His lotus feet.
Purport: 

Some creatures are born from embryos, some from perspiration, and some from seeds. In this way, all living entities emanate from the guṇa-avatāra of the Supreme Personality of Godhead. Ultimately, the Supreme Personality of Godhead is the shelter of all living entities.
