Yoga, meditation
Yoga coming from esoteric practices that are thousands of years old. It has developed several branches to accommodate different personality styles.
The major yogas are Bhakti (a devotional approach that opens the heart, it is best for those who are primarily emotionally-oriented), Jnana (an intellectual approach that leads to wisdom, it is best for those who are primarily mentally-oriented), Karma (an active, service-oriented approach, it is best for those who are more extroverted and who find meaning mostly through relationship), and Raja (a meditational approach, it is best for those who are primarily oriented to the practical aspects of a situation).
In India, Yoga is considered one of the six branches of classical philosophy and is referred to throughout the Vedas - ancient Indian scriptures and amongst the oldest texts in existence.The Upanishads are also broadly philosophical treatises which postdate the Vedas and deal with the nature of the "soul" and universe.
However, the origins of yoga are believed to be much older than that, stemming from the oral traditions of Yogis, where knowledge of Yoga was handed down from Guru (spiritual teacher) to Sisya (spiritual student) all the way back to the originators of Yoga, "the Rishis," who first began investigation into the nature of reality and man's inner world.
