Commentary

Bhagavad Gita 13:5 establishes the authority and pedigree of the teaching Krishna is about to give. Before describing the field and its knower, He points out that this knowledge is not new or invented — it has been expressed by great sages in many ways, elaborated in the Vedic hymns, and rigorously demonstrated through the logical aphorisms of the Brahma Sutra.

Rishibhih Bahudhaa Geetam — Sung by Many Sages

The rishis — the ancient seers of truth — perceived these realities through deep meditation and recorded them. Different sages approached the subject from different angles, using different metaphors and frameworks, but all arrived at the same essential truths about matter and spirit, the field and its knower. The diversity of expression does not indicate disagreement; it reflects the richness of the subject.

Chhandobhih — Through Vedic Hymns

The word chhandas refers to the Vedic mantras and hymns — the Upanishads in particular, which form the philosophical core of the Vedas. The Taittiriya Upanishad, the Shvetashvatara Upanishad, the Kathopanishad — all of these explore the nature of the field and its knower. Krishna is situating His teaching within this venerable tradition, not as an innovation but as a crystallization of timeless wisdom.

Brahma Sutra — Logical Certainty

The Brahma Sutra (also called the Vedanta Sutra), composed by Vyasadeva, is the systematic philosophical text that organizes the teachings of the Upanishads into logical aphorisms. Krishna specifically mentions it because the Brahma Sutra provides hetu — reasons, logical arguments — not mere assertions. The knowledge of kshetra and kshetrajna is not based on blind faith; it is supported by careful reasoning and analysis. Some of its key sutras directly address the field, the individual soul, and the Supreme — such as “na viyad-ashruteh” (2.3.2), “naatmaa shruteh” (2.3.18), and “paraat tu tach-chhruteh” (2.3.40).

Why Krishna Cites Authority

By invoking the sages, the Vedas, and the Brahma Sutra, Krishna gives Arjuna — and all future seekers — confidence that this teaching is well-established, multiply attested, and logically rigorous. Spiritual knowledge should be verifiable, not merely believed. The triple authority of revelation (shruti), tradition (rishi-parampara), and reasoning (yukti) gives this teaching the strongest possible foundation.
