Bhagavad Gītā Chapter 15, Verse 1: Krishna to Arjuna — Puruṣottama-Yoga
The sages speak of an eternal sacred fig rooted above and branching downward, its leaves the Vedic hymns; whoever knows this tree knows all the Vedas.
Bhāṣyakāra purports
- Śaṅkaraadvaita
The Lord declares: this samsara is an inverted asvattha (pipal tree) — its root is upward, in avyakta-Brahman (the unmanifest, causally prior, luminous ground), and its branches spread downward as mahat, ahankara, tanmatras, and the five elements. It is called asvattha because it cannot stand even till tomorrow — every moment it perishes and reconstitutes. Yet as a beginningless stream of birth-body-death it is avyaya (inexhaustible). The Vedas (chandamsi) are its protective leaves: they sustain samsara by prescribing dharma and adharma, cause and fruit. One who truly knows this tree — root, trunk, branches, and leaves together — knows the meaning of all the Vedas, for nothing knowable remains outside this totality.
divergence: Shankara uniquely frames the Vedas as sustaining samsara (not liberating from it directly); liberation comes only by cutting the tree with the sword of jnana. The root is nirguna-Brahman veiled by Maya.
- Rāmānujaviśiṣṭādvaita
The Blessed Lord speaks: the Shruti itself proclaims this asvattha of samsara as urdhva-mula, its root above in the four-faced Brahma (Hiranyagarbha) who resides beyond the seven worlds, and its branches descend to the lowest insects and immovable plants. It is avyaya because, until right knowledge (samyag-jnana) fully arises and cuts attachment, it flows on unbroken. Its leaves are the Vedic injunctions — 'offer the white animal for prosperity, perform the eleven-oblation rite for progeny' — the kama-karmas that nourish and expand the tree just as leaves nourish a living tree. Knowing this tree means knowing the Veda's own purpose: to describe what must be cut and to point toward the cutting.
divergence: Ramanuja locates the root cosmologically in Brahma at the apex of the created order — a personal, hierarchical universe — not in nirguna-Brahman. The Vedas are nourishing leaves, not merely protective ones.
- Madhvadvaita
The Supreme Lord declares homage to the field of samsara. Vishnu is urdhva — supremely high, utterly pure — and He is the root; the created beings are the downward branches, each in their gradated station. This world is asvattha: it does not stand the same even for a single day, yet as a flowing continuation it does not diminish — just as existence in prior cosmic cycles holds its form, so avyayata (inexhaustibility) is maintained through the Lord's sustaining will. The Vedic meters (chandamsi) are leaves because fruit (karma-phala) cannot arise without leaves having first appeared; the Vedas as instruments of fruit-production are thus prior conditions, not ornaments.
divergence: Madhva uniquely identifies the root as Vishnu himself (not Maya or Brahma), grounds avyayata in Vishnu's sovereign will across cosmic cycles, and treats chandamsi as causally prior conditions for karmic fruit — a tighter causal logic than the other schools.
- Vallabhaśuddhādvaita
Sri Bhagavan speaks: this asvattha of varied name-and-form — rooted in Brahma at its top, spreading to all creatures — is none other than the Lord's own lila-prasada-prapancha (the play-manifestation of His grace). The tree is the Lord's own sat-cid portion expanding outward; the world is not illusion but the actual expression of His limitless beauty. One single seed of Brahman expands into cosmic trees bearing countless fruits, each fruit containing countless seeds — an infinite, beginningless process that is also the Lord's own form. The Vedic hymns are shady, pleasure-giving leaves for the jivas: externally they promote kama-karmas, but inwardly they point toward the bliss-station that is unmixed with sorrow. To know this tree is to know the Veda's secret — that samsara is Bhagavan's own karyam (effect-body) and only His grace can dissolve the knot of ahamkara that makes us mistake the branch for the root.
divergence: Vallabha alone treats the inverted tree as a positive theophany — the world is real and sacred as Krsna's own body, not a threatening illusion. Avyayata is the Lord's inexhaustible creative abundance, not a problem to escape.
- Śrīdharabhakti
The Blessed Lord teaches vairagya (dispassion) before jnana or bhakti can take root. This asvattha-samsara has Purushottama — He who is superior to both kshara (mutable) and akshara (immutable) — as its root above, and the created intermediaries (Hiranyagarbha and the rest) as its branches below. It is asvattha because it cannot be trusted even till tomorrow; yet as a stream it is avyaya, self-renewing. The Vedas as chandamsi are its leaves because through dharma-adharma prescription they provide the shade of karma-phala that makes all beings cling to the tree. The one who knows this tree in full — its root as Ishvara-Narayana, its branches as Brahma-and-others, its impermanence in individual form, its permanence as stream, its nourishment by Vedic rites — that one alone truly knows the Veda's meaning and is rightly praised as veda-vid.
divergence: Sridhara uniquely names the root as Purushottama-Narayana (not generic Brahman), uses the tree as a vairagya-teaching instrument, and frames veda-vid as high praise earned by grasping samsara whole rather than by textual mastery.
- Madhusūdanaadvaita-bhakti
Sri Bhagavan opens Chapter 15 to resolve Arjuna's awe-struck silence after hearing 'I am the ground of Brahman': the entire chapter is an expanded commentary on that single declaration. The urdhva-mula is Brahman — either as the eternally self-luminous supreme ground that remains unshaken through all samsaric superimposition, or as Maya-conditioned avyakta-Brahman from which the tree springs. Its downward branches are the creative modifications beginning with Hiranyagarbha; it is asvattha — unreliable, perishing moment to moment — yet avyaya as a beginningless-endless continuum of body-lineages. The karma-kanda hymns are leaves that protect (chad — to cover) the tree by veiling the truth and sustaining samsara's machinery. Knowing this tree with its Maya-root is knowing both the karma-Veda and the brahma-Veda at once; only then, armed with the sword of 'aham brahmasmi,' can one cut it and never return.
divergence: Madhusudana alone holds the two readings of the root simultaneously (nirguna-Brahman AND Maya-conditioned Brahman) and ties the tree-image directly to the prior verse 'brahmanah pratishthaham' — the whole chapter as theological footnote to one line.
