7 (19), Bhagavad Gita: Chapter 18, Verse 7

नियतस्य तु सन्न्यास: कर्मणो नोपपद्यते |

मोहात्तस्य परित्यागस्तामस: परिकीर्तित: ||

niyatasya tu sannyāsaḥ karmaṇo nopapadyate
mohāt tasya parityāgas tāmasaḥ parikīrtitaḥ

भावार्थ:

(निषिद्ध और काम्य कर्मों का तो स्वरूप से त्याग करना उचित ही है) परन्तु नियत कर्म का (इसी अध्याय के श्लोक 48 की टिप्पणी में इसका अर्थ देखना चाहिए।) स्वरूप से त्याग करना उचित नहीं है। इसलिए मोह के कारण उसका त्याग कर देना तामस त्याग कहा गया है॥7॥

Translation

Prescribed duties should never be renounced. Such deluded renunciation is said to be in the mode of ignorance.

English Translation Of Sri Shankaracharya’s Sanskrit Commentary By Swami Gambirananda

18.7 Therefore, sannyasah, the abandoning; niyatasya tu karmanah, of the daily obligatory acts, by the seeker of Liberation who is as yet unenlightened and is fit for rites and duites; na apapadyate, is not justifiable, because what is desired is the purification of unenlightened persons. Parityagah, giving up; tasya, of that, of the daily obligatory duty; mohat, through delusion, through ignorance; parikirtitah, is declared; to be tamasah, based on tamas.
Niyata is that duty which must be performed. That an act is niyata (obligatory) and it is relinished is contradictory. Therefore the giving up of that through delusion is declared to be based on tamas, for delusion is tamas.
