Sutra 3.2.39

39. For the same reasons Jaimini (thinks it to be) religious action.

For the same reasons, viz. possibility and scriptural declaration, the teacher Jaimini thinks that religious works, viz. sacrifices, gifts, offerings, and meditation, of themselves bring about their rewards. For we observe that in ordinary life actions such as ploughing and the like, and charitable gifts and so on, bring about their own reward, directly or indirectly. And although Vedic works do not bring about their rewards immediately, they may do so mediately, viz. by means of the so-called apūrva. This follows also from the form of the Vedic injunctions, such as 'He who is desirous of the heavenly world is to sacrifice.' As such injunctions enjoin sacrifices as the means of bringing about the object desired to be realised, viz. the heavenly world and the like, there is no other way left than to assume that the result (which is seen not to spring directly from the sacrifice) is accomplished by the mediation of the apūrva.
