Consider the example of anumana given below: (a) The mountain is fiery. (b) Because it has smoke. (c) Wherever there is smoke, there is fire. Which one of the following expresses Vyapti (the relation of invariable concomitance)?

Vyapti here is the invariable concomitance between smoke and fire.

Step (b) supplies smoke as the mark on the mountain.

Step (c) states that wherever there is smoke there is fire.

This universal tie holds between the mark, smoke, and the inferred, fire.

It is this relation of smoke to fire that licenses the inference, not smoke to mountain.

The invariable concomitance of the middle with the major is vyapti.
