niyatasya tu sannyāsaḥ karmaṇo nopapadyate mohāt tasya parityāgas tāmasaḥ parikīrtitaḥ
It is not right to give up actions which are obligatory; and if they are misunderstood, it is the result of sheer ignorance.
Translated by Shri Purohit Swami
Verily, the renunciation of obligatory action is not proper; the abandonment of the same out of delusion is declared to be Tamasic.
Translated by Swami Sivananda
