Bhagavad Gita · Karma YogaChapter 3, Shloka 25 (3.25)

Outwardly the same, inwardly different. The action looks the same; the motive differs — for the unknowing, "asya karmaṇaḥ phalaṃ mama bhaviṣyati" (Shankara) — "the fruit of this action will be mine"; for the wise — the good of the world.

Shankaracharya: vidvān ātmavit — the knower of the self; cikīrṣuḥ kartum icchuḥ loka-saṅgraham — wishing to bring about the welfare of the world. And the conclusion: loka-saṅgrahaṃ muktvā — apart from the welfare of the world, the knower of the self has no duty.

Acharya Ramanuja — who is "avidvān", who is "vidvān"? Avidvāṃsaḥ = ātmani akṛtsna-vidaḥ — those who do not fully know the self, who are not eligible for jnana-yoga but are eligible for karma-yoga — they practise karma-yoga for the vision of the self. Vidvān = one who fully knows the self and is fit even for jnana-yoga — but, being vyapadeśyaḥ śiṣṭaḥ — regarded as an exemplar — for the protection of the world, wishing to establish through his own conduct the certainty about dharma among good people, karma-yogam eva kuryāt — should practise karma-yoga alone.
