The Highest Spirit, Purushottama, being the Infinite Consciousness, it is the ‘All-knower’, inasmuch as whenever anything is known through perception, feeling, or thought, it is the Principle of Consciousness that illumines it. One who has transcended one’s matter-equipments and has successfully sought and discovered one’s spiritual nature as the Infinite Consciousness, that individual, as the Supreme Awareness, is indicated here as the “All-knower” (Sarvavit).
