After the verb mṛṣ 'to bear', preceded by pari , parasmaipada is used when the fruit of the action accrues to the agent.,
The root मृष \to suffer\ is svaritet, and by sutra 1.3.72 it would have taken Atmanepada termination when the fruit of the action accrued to the agent. This ordains parasmaipada instead.
