“नपुंसकम् इति ज्ञात्वा तां प्रति प्रहितं मनः ।

रमते तच् च तत्रैव हताः पाणिनिना वयम् ।। (SRK 478)

Knowing that ‘mind’ is neuter, I sent mine to her; but now it refuses to return; I’ve been ruined by Pāṇini.

(Pāṇini, was a Sanskrit grammarian from ancient India. The word for mind, manas, is of neuter gender in Sanskrit.)”
