1. Then he said to them: ‘Verily, indeed, you here eat food, knowing this Universal Ātman (Soul) as if something separate. He, however, who reverences this Universal Ātman (Soul) that is of the measure of the span —thus, [yet] is to be measured by thinking of oneself —he eats food in all worlds, in all beings, in all selves.

5.18.2

tasya ha vā etasyātmano vaiśvānarasya mūrdhaiva sutejāś cakṣur (S S )viśvarūpaḥ prāṇaḥ (S S ) pṛthagvartmātmā saṃdeho (S S )bahulo (S ) eva rayiḥ (S ) ura eva vedir lomāṇi (S S )barhir hṛdayaṃ (S S )gārhapatyo mano (S S ) anvāhāryapacana āsyam (S S )āhavanīyaḥ \\518.2\

2. The brightly shining [heaven] is indeed the head of that Universal Ātman (Soul). The manifold [sun] is his eye. That which possesses various paths [i. e. the wind] is his breath. The extended [space] is his body. Wealth [i. e.

water] is indeed his bladder. The support [i. e. the earth] is indeed his feet. The sacrificial area is indeed his breast. The sacrificial grass is his hair. The Gārhapatya fire is his heart. The Anvāhāryapacana fire is his mind. The Āhavanīya fire is his mouth.
