It is a scientific system designed to bring the practitioners health, happiness, and a greater sense of Self. In Yoga, the body and mind are linked to create a state of internal peacefulness and integration, bringing the individual from a state of separation to a self-unity that is flexible, accepting and whole.
Tai Chi originates in China. It is a Chinese Taoist martial art form combines mental concentration, coordinated breathing and slow, graceful body movements to increase well-being, lessen stress, and strengthen the body. The gentle movements and postures in Tai Chi are designed to achieve a harmonious flow of energy (chi) in the body. Chi Kung works on a similar level to Tai Chi, and is a breathing exercise that cultivates chi and transmits it to all the bodily organs. Chi Kung is known in ancient China as "the method to repel illness and prolong life."
