Gyaan yoga, also known as Gyaan Marg, is one of the three spiritual paths in Hinduism, which emphasizes the "path of knowledge", also known as the "path of self-realization". It is one of the three classical paths ("margas") for moksha (salvation, liberation). The other two are karma yoga (path of action, "karmamarga") and bhakti yoga (path of loving devotion to a personal god, "bhaktimarga"). Modern interpretations of Hindu texts have yielded systems, techniques and formulations such as raja yoga and kriya yoga, sometimes misunderstood as additional spiritual paths.
