types of Yoga ,

There are four paths of Yoga: 1) Jnana, the path of knowledge or wisdom; 2) Bhakti, the path of devotion; 3) Karma, the path of action; and 4) Raja, the path of self control. Hatha Yoga, which includes postures and breathing, and is the form most popular in the West, is actually part of Raja Yoga, the path of self control. The path most followed in India is Bhakti Yoga, the path of devotion. Within Hatha Yoga there are many styles, such as Iyengar, Astanga, Integral, Kripalu and Jiva Mukti, to name a few. These styles all share a common lineage back to Patanjali's Yoga Sutras, a text outlining the basic philosophy and practices of Classical Yoga. It was written sometime between the second century B.C. and the first century A.D.
