According to the Mīmāṃsā school, especially in its Bhāṭṭa sub-school, each prescription needs to have a goal, which is independently desirable. Without a goal, a prescription is purposeless and meaningless (anarthaka). Does it also mean that it must have only one goal?
Within the discussion on the need to study Mīmaṃsā, Veṅkaṭanātha discusses the prescription which would promote such duty. He discusses at length whether the injunction to learn by heart the Vedas (svādhyāyo ‘dhyetavyaḥ) could be considered responsible also for the duty to study Mīmāṃsā or whether it stops its functioning at the learning by heart of the Vedic phonemes, without the need to undertake a systematic study of its meaning, as it happens within Mīmāṃsā. This leads to further discussions about the purpose of the injunction to learn. Can it really aim only at learning by heart the phonic form of the Veda? How could this be considered to be an independently desirable goal? By contrast, grasping the meaning of the Veda could be a goal in itself, because it enables one to perform useful Vedic sacrifices. In this connection, Veṅkaṭanātha notes that learning by heart the phonemes cannot be a goal and adds a cryptic remark:
svādhyāyārthabodhayos tu bhāvyatve vidhyānarthakyaprasaṅgāt (Seśvaramīmāṃsā ad PMS 1.1.1, 1971 p. 21)
Because, if both the [learning by heart] of one’s portion of the Veda and the understanding of its meaning were the goal to be realised, the prescription would end up being purposeless
What does this mean? Is a prescription meaningless when it has two purposes?
