4.3
स एवायं मया तेऽद्य योगः प्रोक्तः पुरातनः ।
भक्तोऽसि मे सखा चेति रहस्यं ह्येतदुत्तमम् ॥
స ఏవాయం మయా తేఽద్య యోగః ప్రోక్తః పురాతనః ।
భక్తోఽసి మే సఖా చేతి రహస్యం హ్యేతదుత్తమమ్ ॥
sa evāyaṃ mayā te’dya yogaḥ proktaḥ purātanaḥ |
bhakto’si me sakhā ceti rahasyaṃ hyetaduttamam ||
About chapter 4
Krishna reveals that this yoga is ancient, and that he takes birth age after age to protect the good and restore dharma (4.7–4.8). He explains how to see inaction in action, the many forms of yajña, and why knowledge is the purest of all things. Knowledge is gained by humble enquiry and service to a teacher, and it burns away the effects of past action.
