Commentary

The fifteenth chapter of the Bhagavad Gita opens with one of the most striking metaphors in all of Vedic literature: the ashvattha tree — an eternal banyan with its roots growing upward and its branches spreading downward. This image is drawn from the Katha Upanishad and represents the entire material world as an inverted tree.

Why inverted? Because the roots of this material existence lie in the highest realm — Brahmaloka, the world of Brahma — and from there the tree expands downward into the various planetary systems and species of life. The real source of everything is the Supreme, who exists above all. The material world is thus a reflection of the spiritual reality, much like a tree reflected in water appears upside-down.

The leaves of this tree are the Vedic hymns (chhandaamsi). Just as leaves nourish a tree through photosynthesis, the Vedic rituals and ceremonies nourish and sustain the material world. One who is attracted to the beautiful leaves — the rituals promising heavenly pleasures — never reaches the root of the tree. But one who understands the entire structure of this tree, from root to branch to leaf, is said to be vedavit — the true knower of the Vedas.

Krishna’s message is clear from the very first verse: the purpose of Vedic knowledge is not to enjoy the fruits of material life endlessly, but to understand the tree of material existence and ultimately transcend it. The one devoted to Krishna already knows the Vedas in their essence.
