Bhagavad Gita · Akshara Brahma YogaChapter 8, Shloka 19 (8.19)

Shankaracharya. Sa eva ayaṃ nānyaḥ — the same, not another (the continuity of the fruits of action: akṛtābhyāgama-kṛta-vipraṇāśa-doṣa-parihārārtham — to avoid the faults of receiving fruit for what was not done and of losing the fruit of what was done, end of 8.18); avaśaḥ asvatantra eva — wholly dependent; avidyādi-kleśa-mūla-karmāśaya-vaśāt — under the sway of the store of karmic impressions rooted in the afflictions such as ignorance (end of 8.18).

Acharya Ramanuja. Sa eva ayaṃ karma-vaśyo bhūta-grāmaḥ — the same multitude of beings, under the sway of karma; in the great dissolution, pṛthivī apsu pralīyate āpaḥ tejasi līyante ity-ādi-krameṇa avyaktākṣara-tamaḥ-paryantaṃ mayi eva pralīyante — earth into water, water into fire… up to the unmanifest, the akshara and tamas — finally dissolving into me; therefore aiśvarya-gatiṃ prāptānāṃ punarāvṛttiḥ aparihāryā, mām upetānāṃ tu na — for those who attain power, return is unavoidable; for those who reach me, it is not. Further: kaivalya-prāptānām api punarāvṛttiḥ na vidyate — those who attain kaivalya do not return either (8.20–8.21).
