Integral Yoga is a system of yoga that claims to synthesize six branches of classical Yoga philosophy and practice: Hatha, Raja, Bhakti, Karma, Jnana, and Japa yoga. It was brought to the West by Swami Satchidananda, the first centre being founded in 1966. Its aim is to integrate body, mind, and spirit, using physical practices and philosophical approaches to life to develop the physical, emotional, intellectual, and spiritual aspects of individuals. The system includes the practices of asana, pranayama, and meditation to develop physical and mental stillness so as to access inner peace and joy, which Satchidananda believed was a person's true nature. It also encourages practitioners to live service-oriented lives.

Hatha yoga is a branch of yoga that uses physical techniques to try to preserve and channel vital force or energy. The Sanskrit word हठ haṭha literally means "force", alluding to a system of physical techniques. Some hatha yoga style techniques can be traced back at least to the 1st-century CE, in texts such as the Hindu Sanskrit epics and Buddhism's Pali canon. The oldest dated text so far found to describe hatha yoga, the 11th-century Amṛtasiddhi, comes from a tantric Buddhist milieu. The oldest texts to use the terminology of hatha are also Vajrayana Buddhist. Hindu hatha yoga texts appear from the 11th century onward.
