2.132

"For the secret [mudrā], make an internal bind, erect the fire wheels and spread them apart;
the two space [fingers] hold the sides of the wind [fingers]. To the right, visualize the noble Ratnākara:
wisdom is spread, space and wind [form] a jewel, and atop the jewel is a three-spoke mudrā.
Ratnapāṇi has atop a jewel a single-spoke vajra mudrā,
the wisdom fist extending the water wheel (space presses three). To the right of Dharaṇīṃdhara, atop a jewel,
is the two-hand vajra mudrā. Ratnamudrāhasta has atop a jewel
a five-spoke vajra mudrā. To the right of Dṛḍhādhyāśaya, atop a jewel,
is the karmavajra mudrā: concentration and wisdom join in a lotus,
with the space [fingers] side-by-side, slightly raised and opened."
