Bhagavad Gita 18.4
निश्चयं शृणु मे तत्र त्यागे भरतसत्तम । त्यागो हि पुरुषव्याघ्र त्रिविधः सम्प्रकीर्तितः ॥
niścayaṃ śṛṇu me tatra tyāge bharata-sattama / tyāgo hi puruṣa-vyāghra tri-vidhaḥ samprakīrtitaḥ
Translation
Hear my verdict on relinquishment, best of the Bharatas. Relinquishment, O tiger among men, is declared to be of three kinds.
Reflection
Before reading further, which of your recent renunciations was actually escape dressed up as wisdom?
Read this verse in its chapter: Chapter Eighteen
Krishna now gives the structuring move that will run through this entire chapter. Tyaga, like food and worship and austerity before it, comes in three flavors, sattvika, rajasika, tamasika. The student needs a map, not a slogan. By telling Arjuna up front that tyaga itself is threefold, Krishna is signaling that the question is not whether to renounce but which renunciation is real. Two of the three coming kinds will look like renunciation but will not deliver freedom. Only one will. The rest of the early verses unpack which is which.
