Chāndogya Upaniṣad 3.14: Śāṇḍilyavidyā

3.14.1

sarvaṃ khalv idaṃ brahma tajjalān iti śānta upāsīta \
atha khalu kratumayaḥ puruṣo yathākratur asmiṃl loke puruṣo bhavati tathetaḥ pretya bhavati \
sa kratuṃ kurvīta \\314.1\

1. 'Verily, this whole world is Brahma. Tranquil, let one worship It as that from which he came forth, as that into which he will be dissolved, as that in which he breathes.

Now, verily, a person consists of purpose (_kratu-maya_). According to the purpose which a person has in this world, thus does he become on departing hence. So let him form for himself a purpose.

3.14.2

manomayaḥ prāṇaśarīro bhārūpaḥ satyasaṃkalpa ākāśātmā sarvakarmā sarvakāmaḥ sarvagandhaḥ sarvarasaḥ sarvam idam abhyatto 'vāky anādaraḥ \\314.2\

2. He who consists of mind, whose body is life (_prāṇa_), whose form is light, whose conception is truth, whose soul (_ātman_) is space, containing all works, containing all desires, containing all odors, containing all tastes, encompassing this

3.14.3

eṣa ma ātmā antarhṛdaye aṇīyān vrīher vā yavād vā sarṣapād vā śyāmākād vā śyāmākataṇḍulād vā \
eṣa ma ātmā antarhṛdaye jyāyān pṛthivyā jyāyān antarikṣāj jyāyān divo jyāyān ebhyo lokebhyaḥ \\314.3\

whole world, the unspeaking, the unconcerned— this Soul of mine within the heart is smaller than a grain of rice, or a barley-corn, or a mustard-seed, or a grain of millet, or the kernel of a grain of millet ; this Soul of mine within the heart is greater than the earth, greater than the atmosphere, greater than the sky, greater than these worlds.

3.14.4

sarvakarmā sarvakāmaḥ sarvagandhaḥ sarvarasaḥ sarvam idam abhyatto 'vākyanādaraḥ \
eṣa ma ātmā antarhṛdaye \
etad brahma \
etam itaḥ pretyābhisaṃbhavitā asmīti yasya syād addhā na vicikitsā asti \
iti ha smāha śāṇḍilyaḥ śāṇḍilyaḥ \\314.4\

4. Containing all works, containing all desires, containing all odors, containing all tastes, encompassing this whole world, the unspeaking, the unconcerned—this is the Soul of mine within the heart, this is Brahma. Into him I shall enter on departing hence.

If one would believe this, he would have no more doubt.—Thus used Śāṇḍilya to say—yea, Śāṇḍilya!
