ऋषिभिर्बहुधा गीतं छन्दोभिर्विविधैः पृथक् | ब्रह्मसूत्रपदैश्चैव हेतुमद्भिर्विनिश्चितैः || ५ ||
ṛṣibhir bahudhā gītaṁ chandobhir vividhaiḥ pṛthak brahma-sūtra-padaiś caiva hetumadbhir viniścitaiḥ
ṛṣibhiḥ—by the sages; bahudhā—in many ways; gītam—described; chandobhiḥ—by Vedic hymns; vividhaiḥ—various; pṛthak—separately; brahma-sūtra-padaiḥ—by the aphorisms of the Brahma-sutras; ca—also; eva—certainly; hetumadbhiḥ—with reasoning; viniścitaiḥ—conclusively.
“This has been sung by sages in many ways and in various Vedic hymns separately, and also in the well-reasoned and conclusive words of the Brahma-sutras.”
Krishna situates His teaching within the entire tradition of Indian spiritual inquiry. The 'rishis in many ways' refers to the Upanishads; the 'various Vedic hymns' refers to the Rig Veda and others; the 'Brahma-sutra-padais' refers to Badarayana's systematic philosophical aphorisms. This verse is significant because it positions the Gita as the synthesis (prasthana-traya) of the entire Vedantic tradition — completing the triple canon of Upanishads, Brahma Sutras, and the Gita itself.
The teaching of the Field and its Knower is not new; it has been sung in countless ways across millennia because it addresses the deepest and most persistent human question. Study the tradition broadly — different teachers often illuminate the same truth from angles that will resonate with your particular mind. No single formulation exhausts the truth.
