When he recites the mantras a मान्त्रिक should use different kinds of gestures with his hands to suit the recital. They are called मुद्रास् . The मुद्रास् in general are given below:

The first mudrā is called अञ्जलिमुद्रा . अञ्जली means a cavity formed by folding the hands and joining the open hands together. If the hands thus folded are placed on the breast it becomes a वन्दिनी मुद्रा . The hands should be placed on the breast with a slight slant to the left for वन्दिनी मुद्रा . The third mudrā is called ऊर्द्ध्व मुद्रा . Hold the left hand first in such a way that the thumb comes on the top and then with the fingers of the right hand bind the thumb of the left hand. The thumb of the right hand should also come to the top. This is called ऊर्द्ध्व मुद्रा . The lowering of the left palm opened up is called वराहमुद्रा . (Chapter 26, Agni Purāṇa)
