ऊर्ध्वमूलम् अधःशाखम् अश्वत्थं प्राहुर् अव्ययम् । छन्दांसि यस्य पर्णानि यस् तं वेद स वेदवित् ॥
ūrdhva-mūlam adhaḥ-śākham aśvatthaṃ prāhur avyayam | chandāṃsi yasya parṇāni yas taṃ veda sa veda-vit ||
Saṃsāra is an eternal inverted tree rooted in Brahman; knowing this tree root to tip is true Vedic wisdom.
Word by word (3)
- ūrdhva-mūlam adhaḥ-śākham
- — root above (ūrdhva = upward), branches below (adhas = downward) — the inverted cosmic tree, Brahman as root
- aśvattham prāhur avyayam
- — they call (prāhur) the aśvattha indestructible (avyayam) — the fig tree as symbol of saṃsāra, ever-changing yet metaphysically persistent
- chandāṃsi yasya parṇāni yas taṃ veda sa veda-vit
- — whose leaves are the Vedic metres (chandas); he who knows THIS tree — that one is the true Veda-knower (veda-vit)
They speak of an imperishable aśvattha tree with its root above and branches below, whose leaves are the Vedic metres. One who truly knows this tree is the real knower of the Vedas.
A modern analogy
Imagine a vast banyan tree reflected in still water — what appears to be the top is actually the bottom, and what seems solid dissolves when you disturb the surface. Saṃsāra is exactly like this reflection: real enough to live in, unreal when looked at from the source.
Ch.15 opens the Puruṣottama Yoga with this striking cosmological symbol drawn from the Kaṭha Upaniṣad (2.3.1): 'ūrdhva-mūlo 'vak-śākha eṣo 'śvatthaḥ sanātanaḥ.' After Ch.14's analysis of guṇa-bondage, Ch.15 now shows HOW to understand saṃsāra symbolically — and then transcend it. The aśvattha with root above is the entire manifest world, whose ultimate source is the Unmanifest.
The image is philosophically precise: Brahman (ūrdhva = the Highest) is the root — the cause — while the entire phenomenal world hangs downward as branches and leaves. The word avyaya (imperishable) applies to this world-tree AS SYMBOL, not as material reality. Each branch is a level of existence; the leaves/Vedas are the protective knowledge-layer. One who understands the tree's structure — cause-effect, Brahman-as-root — truly understands what the Vedas point to.

Cast off this petty weakness of heart — rise. This is not who you are.
Transcending the three guṇas, the embodied one is freed from birth-death-age-pain and attains immortality.
Arjuna asks: what does the truly wise person look like? How do they speak, sit, and move?
Deluded by the three guṇa-constituted states, all this world does not recognize Me — beyond them, imperishable.
Taking refuge in Me for liberation from old age and death — they know Brahman, Adhyātma, and all of Karma.
