आगमे विश्वासटिप्पन्यः

In Indian dance, sculpture, and ritual, a
particular symbolic hand gesture
(mudra) in which the tips of the thumb
and index finger are touching, with the
rest of the fingers extended and the
palm facing the viewer. This is the
hand gesture used to signify explanation or exposition. For this reason it is
also known as the vyakhyana (“teaching”) mudra and the sandarshana
(“expository”) mudra.
