Bhagavad Gita · Karma YogaChapter 3, Shloka 16 (3.16)

Three descriptions. (1) Aghāyuḥ — one whose life is spent in sin; (2) indriyārāmaḥ — one whose "pleasure garden" (playground) is the senses and their objects; (3) mogham jīvati — lives in vain.

Shankaracharya: Ishvara set the wheel of the world in motion through the Veda and yajña; one who is karmaṇi adhikṛtaḥ — eligible for action — and does not keep it turning is pāpa-jīvanaḥ (living a sinful life). The gist of this section: tasmāt ajñena adhikṛtena kartavyam eva karma — therefore the eligible unknowing person must indeed perform action — until fitness for steadfastness in knowledge of the self arrives.

Acharya Ramanuja — the full form of the wheel, and the "garden". The wheel: from food, the living body; from the body, action; from action, yajña; from yajña, rain; from rain, food — anyonya-kārya-kāraṇa-bhāvena cakravat — turning like a wheel, each the effect and cause of the other. Whoever is engaged in spiritual practice — karma-yogādhikārī jñāna-yogādhikārī vā — whether eligible for karma-yoga or for jnana-yoga — and does not sustain the body on the remains of yajña is aghāyu. And indriyāṇi eva asya udyānāni bhavanti — the senses themselves become his "gardens and orchards"; he is not ātmārāma (delighting in the self) but indriyārāma (delighting in the senses). For such a person even the effort at jnana-yoga and the like is atiniṣphala — utterly futile.
