A short, dense chapter, often chanted before meals. The world is an eternal tree with its roots above and its branches below; cut it with the axe of detachment and seek the place no sun lights. The soul is an eternal fragment of God, carrying the senses from body to body as the wind carries scent. And beyond both the perishable and the imperishable is the Supreme Person, Purushottama.
The world is an ashvattha tree with its roots above in the source and its branches spreading below, its leaves the Vedic hymns (15.1). No one sees where it begins or ends. Cut it down with the strong axe of detachment, and seek the place that neither sun nor moon nor fire lights (15.6).
ūrdhvamūlamadhaḥśākhamaśvatthaṃ prāhuravyayam chandāṃsi yasya parṇāni yastaṃ veda sa vedavit
They speak of an imperishable ashvattha tree with its roots above and its branches below; its leaves are the Vedic hymns. Whoever knows it knows the Vedas.
Its branches spread below and above, nourished by the qualities, its buds the objects of the senses; and below, its roots stretch out, binding to action in the world of men.
na rūpamasyeha tathopalabhyate nānto na cādirna ca saṃpratiṣṭhā aśvatthamenaṃ suvirūḍhamūla masaṅgaśastreṇa dṛḍhena chittvā
Its real form is not seen here, nor its end, nor its beginning, nor its foundation. Cutting down this firmly rooted ashvattha with the strong axe of detachment,
one should then seek that place from which, once reached, no one returns, thinking: "I take refuge in that primal Person from whom this ancient stream of activity flowed forth."
nirmānamohā jitasaṅgadoṣā adhyātmanityā vinivṛttakāmāḥ dvandvairvimuktāḥ sukhaduḥkhasaṃjñai rgacchantyamūḍhāḥ padamavyayaṃ tat
Without pride or delusion, having conquered the fault of attachment, always dwelling in the Self, desires turned away, freed from the pairs of opposites known as pleasure and pain, the undeluded reach that eternal state.
na tadbhāsayate sūryo na śaśāṅko na pāvakaḥ yadgatvā na nivartante taddhāma paramaṃ mama
Neither the sun, nor the moon, nor fire lights it up. Having gone there, they do not return. That is my supreme abode.
Verses 15.7–15.11
As the wind carries scent
The living soul is an eternal fragment of Krishna (15.7). It gathers the senses and the mind, and when it leaves one body for another it carries them along, the way the wind carries scent from a flower (15.8). The deluded don't see it; those with the eye of knowledge do.
An eternal fragment of myself, becoming a living soul in the world of living beings, draws to itself the senses, with the mind as the sixth, which rest in nature.
Striving yogis see it dwelling in themselves; but the unthinking, whose selves are unformed, do not see it even though they strive.
Verses 15.12–15.15
I nourish the plants as the moon
The light of the sun, the moon and fire is his. Entering the earth he sustains all beings; as the nectar-filled moon he nourishes the plants (15.13); as the fire of life he digests food. He sits in every heart, the source of memory and knowledge, and of forgetting too.
I am seated in the hearts of all; from me come memory, knowledge and their loss. I am what is to be known in all the Vedas; I am the author of Vedanta and the knower of the Vedas.
Verses 15.16–15.20
Beyond perishable and imperishable
There are two persons in the world: the perishable, which is all beings, and the imperishable, which never changes. Beyond both is the Supreme Person, who enters and sustains the three worlds (15.16–18). Whoever knows this knows all, and has done all there is to do.
yasmātkṣaramatīto'hamakṣarādapi cottamaḥ ato'smi loke vede ca prathitaḥ puruṣottamaḥ
Since I am beyond the perishable and higher even than the imperishable, I am celebrated in the world and in the Veda as Purushottama, the Supreme Person.
