Purposelessness is an important part of Mudra. One way is to trust space. Our need to constantly adhere to a goal orientation is based in part on our fear of space. So, in Mudra, a challenge for the practitioner is to expose themselves to experiences where they are called upon to trust space. In physical postures, for example, one can experience space as substantial and capable of actually holding up one's body 7.
Tension equals relaxation.
Normally most of us are trying to flee states of tension and find states of relaxation. But in Mudra, tension and relaxation two sides of the same coin and in some sense they are equal. Normally, in the neurotic state, the body represents a patchwork of points of relaxation and points of tension. The two work together to create a sense of cocoon in which the self is experienced as separate from other. Mudra exercises that work with physical postures build a state or total intensification or total relaxation.
