अब्जा गोजा ऋतजा अद्रिजा ऋतं बृहत् ॥ २॥

Lo, the Swan whose dwelling is in the purity, He is the Vasu in the interregions, the Sacrificer at the altar, the Guest in the vessel of the drinking; He is in man and in the Great Ones and His home is in the Law and His dwelling is in the firmament; He is all that is born of water and all that is born of earth and all that is born of the mountains. He is the Truth and He is the Mighty One.

Sri Aurobindo · CWSA 18, p. 120
