Sarva-Vidravini mudra:

Ambika is identified as the triad of vama-jyesta-roudri. While vama is the creative aspect, jyesta strives to sustain the universe that is created.

 Drim is the bija mantra of this mudra, which pervades the sarva-asaparipuraka (fulfiller of all hopes) enclosure of Sri Cakra.

This mudra is presented by pointing, the pointing (tarjani) and middle (madhyama) fingers of both hands and holding the remaining fingers closely together as shown in the above photographs.
