Gīta Bhāshya 5.03

Understand the correct meaning of the word 'saṁnyāsa', i.e. renunciation, is beneficial.

संन्यास शब्दार्थमाह - ज्ञेय इति। संन्यासस्य निःश्रेयसकरत्वं ज्ञापयितुं तच्छब्दार्थं स्मारयति - ज्ञेय इति ॥३॥

saṁnyāsa śabdārthamāha - jñeya iti। saṁnyāsasya niḥśreyasakaratvaṁ jñāpayituṁ tacchabdārthaṁ smārayati - jñeya iti ॥3॥

[saṁnyāsa = 'saṁnyāsa', i.e. renunciate; śabdārthamāha = word meaning is explained; - jñeya iti = by 'jñeya', i.e. understand, verse;। saṁnyāsasya = renunciation is of; niḥśreyasakaratvaṁ = the quality of leading to ultimate good; jñāpayituṁ = to indicate, to convey; tacchabdārthaṁ = that, the meaning of the word; smārayati = recalls, remembers; - jñeya = understand; iti = thus;]

Meaning of the word 'saṁnyāsa' i.e. renunciate, is explained by 'jñeya' verse. To remind (Arjuna) that renunciation is having the quality that leads to ultimate good, (Krishna) explains the meaning of the word by saying - 'understand'.
