Śaṅkaraon Brahma Sūtra 2.3.11

We have to supply from the preceding Sutra the words ‘ thence ’ and ‘ for thus the text — declares.’ Water is pro- duced from fire; for the text says, ‘it sent forth water’ {K/i. Up. VI, 2, 3), and ‘from fire (sprang) water’ (Taitt. Up. II, j). These explicit statements allow no room for doubt The Sfitrakdra, however, having explained the creation of fire, and being about to explain the creation of I.e. it appears from the ’preceding discussion that those passages have to he explained in such a way as to agree with those other passages which state the order of the created beings. * So that the Shtra might possibly be looked upon as not called for. 1 — earth, propounds this Sutra in order to insert water (and thus to point out its position in the sr/sh/ikrama).
