Mahavakyas 3: Ayam Atma Brahma

 Ayam Atma Brahma (अयम् आत्मा ब्रह्म) - "This Self (Atman) is Brahman" (Mandukya Upanishad 1.2 of the Atharva Veda)

sarvaṁ hyetad Brahma ayam-ātmā Brahma.

All this is verily Brahman. This Ᾱtman is Brahman.

(tr-Chinmayananda)

All this is surely Brahman. The Self is Brahman. The Self, such as It is, is possessed of four quarters.

(tr-Gambhirananda)

1. Hariḥ Om. Om, the word, is all this. A clear explanation of it is (the following) – all that is past, present and future, verily, is Om. That which is beyond the three periods of time is also indeed, Om.

2. All this is verily Brahman. This Ᾱtman is Brahman.
