नियतस्य तु संन्यासः कर्मणो नोपपद्यते ।मोहात्तस्य परित्यागस् तामसः परिकीर्तितः ॥
niyatasya tu saṃnyāsaḥ karmaṇo nopapadyatemohāttasya parityāgas tāmasaḥ parikīrtitaḥ
Verily, renunciation of tightly regulated actions is not proper, to renounce them from ignorance is a tamasic renunciation.
Gītā 18·7…it is the rightly regulated action, nityatvakarma, that has to be done, action regulated by the Shastra, the science and art of right knowledge, right works, right living, or regulated by the essential nature, svabhāva-nityatvakarma , or, finally and best of all, regulated by the will of the Divine within and above us. The last is the true and only action of the liberated man, muktasyakarma. To renounce these works is not a right movement—the Gita lays that down plainly and trenchantly in the end, niyatasya tu saṁnnyāsa karmaṇaḥ na upapadyate To renounce them from an ignorant confidence in the sufficiency of that withdrawal for the true liberation is a tamasic renunciation. The gunas follow us, we see, into the renunciation of works as well as into works. A renunciation with attachment to inaction, saṅgo-akarmaṇi, would be equally a tamasic withdrawal.
