Chapter XIII · Śloka 5
ऋषिभिर्बहुधा गीतं छन्दोभिर्विविधैः पृथक् ।
ब्रह्मसूत्रपदैश्चैव हेतुमद्भिर्विनिश्चितैः ॥
ब्रह्मसूत्रपदैश्चैव हेतुमद्भिर्विनिश्चितैः ॥
ṛṣibhir bahudhā gītaṃ chandobhir vividhaiḥ pṛthak |
brahma-sūtra-padaiś caiva hetumadbhir viniścitaiḥ ||
brahma-sūtra-padaiś caiva hetumadbhir viniścitaiḥ ||
This has been sung by the sages in many ways, in various hymns, and also in the well-reasoned and conclusive words of the Brahma-sūtra aphorisms.
Kṛṣṇa grounds His teaching in the authority of the Vedic seers (ṛṣis), the Upaniṣadic hymns, and the logical aphorisms of the Brahma-sūtras, aligning the Gītā with the Vedāntic tradition. He invokes śruti and tarka as dual pramāṇas.
