Chāndogya Upaniṣad 3.12

3.12.1

gāyatrī vā idaṃ sarvaṃ bhūtaṃ yad idam kiṃca \
vāg vai gāyatrī \
vāg vā idaṃ sarvaṃ bhūtaṃ gāyati ca trāyate ca \\312.1\

1. Verily, the Gāyatrī meter is everything here that has come to be, whatsoever there is here. Verily, the Gāyatrī is speech. Verily, speech both sings of (gāyati) and protects (trāyate) everything here that has come to be.

3.12.2

yā vai sā gāyatrīyaṃ vāva sā yeyaṃ pṛthivī \
asyāṃ hīdaṃ sarvaṃ bhūtaṃ pratiṣṭhitam \
etām eva nātiśīyate \\312.2\

2. Verily, what this Gāyatrī is—that is the same as what this earth is; for on it everything here that has come to be is established. It does not extend beyond it.

3.12.3

yā vai sā pṛthivīyaṃ vāva sā yad idam asmin puruṣe śarīram \
asmin hīme prāṇāḥ pratiṣṭhitāḥ \
etad eva nātiśīyante \\312.3\

3. Verily, what this earth is—that is the same as what the body in man here is; for in it these vital breaths are established. They do not extend beyond it.

3.12.4

yad vai tat puruṣe śarīram idaṃ vāva tad yad idam asminn antaḥ puruṣe hṛdayam \
asmin hīme prāṇāḥ pratiṣṭhitāḥ \
etad eva nātiśīyante \\312.4\

4. Verily, what the body in man is—that is the same as what the heart within man here is; for on it these vital breaths are established. They do not extend beyond it.

3.12.5

saiṣā catuṣpadā ṣaḍvidhā gāyatrī \
tad etad ṛcā abhyanūktam \\312.5\

5. This is the four-quartered sixfold Gāyatrī. With reference to it a Rig verse states:—

3.12.6

(S ) asya mahimā \tato jyāyāṃś ca puruṣaḥ \
pādo 'sya sarvā bhūtāni \tripād asyāmṛtaṃ divīti \\312.6\

6. His greatness is of such extent,
Yet Purusha is greater still.
All beings are one fourth of him;
Three fourths, the immortal in the sky.

3.12.7

yad vai tad brahmetīdaṃ vāva tad yo 'yaṃ bahirdhā puruṣād ākāśaḥ \
yo vai sa bahirdhā puruṣād ākāśaḥ \\312.7\

7. Verily, what is called Brahma—that is the same as what the space outside of a person is. Verily, what the space outside of a person is— that is the same as what the space within a person is. Verily, what the space within a person is— that is the same as what the space here within the heart is. That is the Full, the Non-active. Full, non-active prosperity he obtains who knows this.

3.12.8

ayaṃ vāva sa yo 'yam antaḥ puruṣa ākāśaḥ \
yo vai so 'ntaḥ puruṣa ākāśaḥ \\312.8\

3.12.9

ayaṃ vāva sa yo ayam antarhṛdaya ākāśaḥ \
tad etat pūrṇam apravarti \
pūrṇam apravartinīṃ śriyaṃ labhate ya evaṃ veda \\312.9\
