Taittirīyopaniṣat 03.13

One should meditate upon 'That' as foundation — he becomes possessed of firmness. One should meditate upon 'That' as greatness — he becomes great. One should meditate upon 'That' as mind — he becomes endowed with mind. One should meditate upon 'That' as obeisance — desires bow to him. One should meditate upon 'That' as Brahman — he becomes possessed of Brahman. One should meditate upon 'That' as the complete destruction of Brahman's enemies — by complete destruction, enemies and rivals are killed. By complete destruction, unloved hostile relatives are destroyed.

Taittirīya Bhāshya 03.13

Testimonials continue to elaborate how Lord Hari possesses all auspicious qualities.

"He, Lord Hari, is the foundation because of being the establisher, the mind because of being worthy of respect; ever to be saluted as he is worthy of salutation; eternal, and great due to his greatness; he is the destroyer of Brahmā (Viriñci), and he is Brahman because he possesses all qualities."
