Can the Indian yoga systems be brought under this classification? The Way of Knowledge [gnana] culminates the Short Path; the Royal Way of Concentration [raja] culminates the Long Path. The Ways of Religious Devotion [bhakti] and Muttered Affirmation [mantra] belong, in their simple elementary forms, to the Long Path, but in their subtler advanced forms to the Short Path. The Way of Physical Control [hatha] is obviously a Long Path one.
