Atharva Veda 6.111: A charm for insanity

Unbind and loose for me this man, O Agni, who bound and well restrained is chattering folly.
Afterward he will offer thee thy portion when he hath been delivered from his madness.

Let Agni gently soothe thy mind when fierce excitement troubles it.
Well-skilled I make a medicine that thou no larger mayst be mad.

Insane through sin against the Gods, or maddened by a demon's power— Well-skilled I make a medicine to free thee from insanity.

May the Apsarases release, Indra and Bhaga let thee go.
May all the Gods deliver thee that thou no longer mayst be mad.
