5. Now, it has elsewhere been said: 'This, namely *a*, *u*, and *m* [= *Om*], is the sound-form of this [Ātman, Soul].'

Feminine, masculine, and neuter: this is the sex-form.

Fire, wind, and sun: this is the light-form.

Brahmā, Rudra, and Vishṇu: this is the lordship-form.

The Gārhapatya sacrificial fire, the Dakshiṇāgni sacrificial fire, and the Āhavanīya sacrificial fire: this is the mouth-form.

The Rig-Veda, the Yajur-Veda, and the Sāma-Veda: this is the understanding-form.

Earth (*bhūr*), atmosphere (*bhuvas*), and sky (*svar*): this is the world-form.

Past, present, and future: this is the time-form.

Breath, fire, and sun: this is the heat-form.

Food, water, and moon: this is the swelling-form.

Intellect (*buddhi*), mind (*manas*), and egoism (*ahaṃkāra*): this is the intelligence-form.

The Prāṇa breath, the Apāna breath, and the Vyāna breath: this is the breath-form.

Hence these are praised, honored, and included by saying *Om*. For thus has it been said: 'This syllable *Om*, verily, O Satyakāma, is both the higher and the lower Brahma.'
