atha brahmaṇa ādeśāl locaneṣvavasannimiḥ
nimeṣāḥ syuśca lokānāṃ tadviśrāmāya nārada //

With the orders of Brahmâ, Nimi entered the eyes of the mankind, and this causes them to open their eyes; but when Nimi takes rest, they close their eyes; and hence this shutting and closing of the eyes is called winking or nimeṣa. Vasiṣṭha, similarly, entered that pitcher of water and was born out of it, and after him the sage Agastya was born, of the same pitcher, of white colour, with four hands, sacred thread, kamaṇḍalu, and garland.—35-36.
