Taittirīyopaniṣat 01.16 and 17
bhūrit y agnau pratitiṣṭhati। bhuva iti vāyau। suvar ity āditye। maha iti brahmaṇi। āpnoti svārājyam। āpnoti manasaspatim। vākpatiś cakṣuṣpatiḥ। śrotrapatiḥ vijñāna patiḥ। etat tato bhavati ॥16॥
"Bhūḥ" abides in fire, "Bhuvaḥ" in air, "Suvaḥ" in the sun, "Maḥ" in Brahman. He attains his own sovereignty; attains lordship of the mind; lordship of speech; lordship of the eye; lordship of the ear; and lordship of the knowledge. This becomes from that.
ākāśaśarīraṃ brahma. satyātma prāṇārāmaṃ mana ānandam. śāntisamṛddhamamṛtam. iti prācīnayogyopāsva ॥17॥
Brahman has the body of space. Its essence is truth, the abode is breath, and its bliss is that of the mind. It is filled with peace and is immortal. Thus, the ancient and worthy ones meditate upon it.
Taittirīya Bhāshya 01.16 and 17
An ancient testimonial from Brahmasara is quoted, where terminologies in the Upanishad are elaborated with a Pancharatra context. Various auspicious attributes and qualities are those of Lord Vishnu.
aniruddhastu bhūrnāmā hutāśe saṃvyavasthitaḥ। pradyumno bhagavān vāyau bhuva ityeva kīrtitaḥ॥
"But Aniruddha, called Bhū, is established in the fire; Pradyumna, called 'Bhuva', is said to be present in the wind.
saṅkarṣaṇaḥ suvārnāmā sūrye tiṣṭhati keśavaḥ। mahonāmā vāsudevo brahmaṇisthaś caturmukhe॥
Keśava in the form of Saṅkarṣaṇa is renowned as 'Suva' and abides in the sun. The Lord Vāsudeva, named 'Maha', is situated within the four-faced creator, Brahmā.
sa vāsudevaḥ svārājyaṃ vyāpyāsmin manasaspatau। aniruddhe ca saṃvyāptaḥ tato vāgādināṃ patiḥ॥
He, Vāsudeva, pervades his own sovereignty and is the lord of the mind as well, being fully present in Aniruddha; he then becomes the lord of speech and other faculties.
vāgādiṣu sthito nityaṃ bhavatyeṣa janārdanaḥ। svavyāpī ca jagadvyāpī nityaiśvaryāt sa īśvaraḥ॥
Lord Janārdana is ever present in speech and all else; he pervades himself and the world, and by his eternal sovereignty, he is the Lord.
ākāśavad vyāptadehaḥ satyātmā guṇapūrtitaḥ। vāyorviśeṣaramako balānandasvarūpavān॥
His body is like space, which pervades all, whose essence is truth and which is filled with qualities. He delights especially in air, and his nature is strength and bliss.
jñānānanda svarūpo'sau śāntināmā sukhonnateḥ। antagatvāt svataḥ pūrteḥ samṛddhaṃ tat prakīrtitam॥
He, whose essence is knowledge and bliss (jñānānanda) is called Peace (śānti), as he is elevated with happiness. He is called 'samṛddham' i.e. abundant, as he is filled within, on his own, with abundant prosperity.
ityupāsva prāthamiko yogyaḥ tvaṃ mad-upāsane। prādhānyād iti pūrvaṃ hi prāha viṣṇuḥ caturmukham॥
Thus, you are the foremost and worthy of my worship. - thus, Lord Viṣṇu previously taught to the four-faced Brahmā owing to his primacy."
iti brahmasāre॥
- stated thus in Brahmasāra, the essence of Brahman.
