Rāmānujaon Brahma Sūtra 2.1.16

On account of the existence of the posterior, i.e. the effect existing in the cause—for this reason also the effect is non-different from the cause. For in ordinary language as well as in the Veda the effect is spoken of in terms of the cause; as when we say, 'all these things—jars, platters, &c.—were clay only this morning'; or when the Veda says, 'Being only was this in the beginning.'
