Those whose intellect is in That, whose Self is in That, whose support is in That, whose supreme refuge is That, go to non-return, purified of impurity by knowledge.

Totality of dedication. Four aspects of unification: tad-buddhayaḥ — intellect in That; tad-ātmānaḥ — Self in That; tan-niṣṭhāḥ — support in That; tat-parāyaṇāḥ — supreme refuge in That.

Result: apunar-āvṛttim — non-return — to reincarnation. Jñāna-nirdhūta-kalmaṣāḥ — purified of impurity by knowledge — indicates that knowledge is the purifying agent. There is no purification superior to knowledge.
