Sloka 4.38
4.38
न हि ज्ञानेन सदृशं पवित्रमिह विद्यते ।
तत्स्वयं योगसंसिद्धः कालेनात्मनि विन्दति ॥
న హి జ్ఞానేన సదృశం పవిత్రమిహ విద్యతే ।
తత్స్వయం యోగసంసిద్ధః కాలేనాత్మని విన్దతి ॥
na hi jñānena sadṛśaṃ pavitramiha vidyate |
tatsvayaṃ yogasaṃsiddhaḥ kālenātmani vindati ||
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.
