1.5.13

te sukhaprītibahulā bahir antaś ca nāvṛtāḥ
prakāśā bahir antaś ca ūrdhvasrotodbhavāḥ smṛtāḥ //

Beholding this creation also imperfect, Brahmá again meditated, and a third creation appeared, abounding with the quality of goodness, termed Úrddhasrotas. The beings thus produced in the Úrddhasrotas creation were endowed with pleasure and enjoyment, unencumbered internally or externally, and luminous within and without. This, termed the creation of immortals, was the third performance of Brahmá, who, although well pleased with it, still found it incompetent to fulfil his end. Continuing therefore his meditations, there sprang, in consequence of his infallible purpose, the creation termed Arváksrotas, from indiscrete nature. The products of this are termed Arváksrotasas, from the downward current (of their nutriment). They abound with the light of knowledge, but the qualities of darkness and of foulness predominate. Hence they are afflicted by evil, and are repeatedly impelled to action. They have knowledge both externally and internally, and are the instruments (of accomplishing the object of creation, the liberation of soul). These creatures were mankind.
