Yājñavalkya said:: Brahmā had acquired Brahman. (Vedic knowledge) that is imperishable by means of penance. Holy rite is also acquired by means of penance and fame by the holy rite. Again, truthfulness is acquired by splendour and the imperishable Bliss is acquired by truthfulness. The pure, immortal Brahman, the imperishable Bliss, is enveloped and pervaded by Satya (Truth). Brahman alone is called Amṛta (nectar immortal).
