Bhagavad Gita 13.4
ऋषिभिर्बहुधा गीतं छन्दोभिर्विविधैः पृथक्। ब्रह्मसूत्रपदैश्चैव हेतुमद्भिर्विनिश्चितैः॥
ṛṣibhir bahudhā gītaṁ chandobhir vividhaiḥ pṛthak brahma-sūtra-padaiś caiva hetumadbhir viniścitaiḥ
Translation
Sung in many ways by sages, distinctly in various chants, and also in well-reasoned, conclusive verses of the Brahma-sutras.
Reflection
Where in your life are you reinventing a wheel sages already turned?
Read this verse in its chapter: Chapter Thirteen
Pedigree. Before giving his own version, Krishna places it in a lineage. Many sages have sung this distinction. Different meters have carried it. The Brahma-sutra padas have argued it down to reason. The point is not to flatter the tradition. It is to disarm the suspicion that this teaching is novelty. The same content has been turned over for a long time. What is coming next is a compression, not an invention. For a modern listener the line lands sideways: many people have already worked this out. The work today is participation in an old finding, not the manufacture of a new one.
