Within TV ad 1.3.4, (Mimamsadarsana 1929-34, pp. 192–193), Kumārila discusses a seeming deontic conflict and solves it by appealing to the different responsibilities (adhikāra) of the various addressees. He explains that the prescription to learn the Vedas for 48 years does not conflict (virodhābhāva) with the duty to get married and have children, because it addresses people who suffer of disabilities and who therefore cannot become householders. This is a further evidence of how O(x/a) implies that a is actually able to perform x. If a is unable to perform x, the obligation is not incumbent upon them (the background, ableist, assumption is that a blind or lame person cannot support a family.

Kumārila also discusses the prescription to learn the Veda by heart in order to get svarga (heaven/happiness) and explains it would clash against the ones prescribing complicated sacrifices for the same result, since no one would engage in them, if learning the Veda by heart were enough. Here, we see several principles at work:

1. No prescription can remain idle.
2. Translative (?) property of duties: If x implies z and O(x), then O(z). In fact, performing sacrifices \emph{presupposes} learning the Veda by heart, so that O(sacrifices)—>O(learning Veda by heart).

Because of 1., it is clear that the former prescription necessarily only applies to people who cannot perform the latter. Thus: If there are two seemingly contradictory obligations (both aiming at the same result), that is:

(i) O(x/in order to reach s) and
(ii) O (x3/in order to reach s),
then one needs to postulate for the former an additional condition that states something like “Unless you can perform (ii).

As for the converse, namely that prohibitions imply possibility, Śabara (ŚBh ad 1.2.18) explains that the seeming prohibition “The Fire is not to be kindled on the earth, nor in the sky, nor in heaven” cannot be taken as a prohibition, because fire cannot be kindled in the sky nor in heaven.
