("to be established") In Indian philosophy, an element in the accepted form of an inference (anumana).

There are three pieces to an acceptable inference: a statement (pratijna), a rationale (hetu), and an example (drshtanta); each of these three has its own constituent parts.

The sadhya is one of the two elements of the assertion, together with the paksha.

The paksha is the hypothesis's topic and identifies a category of objects, whereas the sadhya is the claim to be demonstrated regarding that category.

The paksha, or class of objects about which a claim is made, in the typical example is "this mountain," and the sadhya, or item to be demonstrated, is "is on fire."
