Bhagavad Gita · 18.4

निश्चयं शृणु मे तत्र त्यागे भरतसत्तम।त्यागो हि पुरुषव्याघ्र त्रिविधः सम्प्रकीर्तितः॥

niśhchayaṁ śhṛṇu me tatra tyāge bharata-sattama tyāgo hi puruṣha-vyāghra tri-vidhaḥ samprakīrtitaḥ

O best of the Bharatas, hear My conclusion regarding tyaga. O tiger among men, tyaga has been declared to be of three kinds.
