Here's a nice video introduction about the paths of yoga which explains the eight different forms of yoga: Hatha, Bhakti, Jnana, Karma, Tantra, Raja, Kriya, and Kundalini. This is a free episode (30 minutess long) of a series by Gaia that then explores each path in turn. https://youtu.be/v3gqJgBSBV4
