Ananda Yoga is a relaxation based practice. However it's important to get the proper perspective on relaxation. 

"It is impossible to develop true Self-Awareness without first learning how to relax. Energy that is bound cannot soar to divine heights. The science of yoga might even be defined as a process of progressive relaxation: first, from outer attachments; then from attachment to the body, to thoughts to personality, to ego. Until one finds himself at last in the stream of infinite life.
