श्रुतोपनिषत्कगत्यभिधानाच्च ॥ १६ ॥
śrutopaniṣatkagatyabhidhānācca || 16 ||
śruta-upaniṣatka-gati—The way of those who have realized the Truth of the Upanishads; abhidhānāt—on account of the statement; ca—also;
16. Also on account of the statement of the way (after death) of those who have known the Truth of the Upanishads (i.e. knowers of Brahman) (with reference to the knower of the person in the eye).
The Devayana path or the path of the gods, by which a knower of Brahman travels after death and which is described in the Prasna Upanishad 1.10 and other scriptural texts, is referred to here. Since the knower of “the person in the eye” also goes by this path after death, and since it is known from scriptures that none other except the knower of Brahman goes by this path after death, “the person in the eye” must be Brahman.
