Sri Chinmoy says Yoga encompasses many Paths, all leading to the Source.
In RSG 14 he writes that there are three principal paths:
- Bhakti Yoga: the path of devotion
- Karma Yoga: the path of action
- Jnana Yoga: the path of knowledge
Also, in Jnana Yoga, the branch that deals with mysticism is called Raja Yoga.
It seems to me that while each path has unique aspects, a few aspects are common to all paths:
- Guidance of the Inner Pilot
- Strict celibacy
- No intoxicants
I do not know much other paths, but I would feel like advicing a sincere seeker to be careful to deal with a path where any one of those four common traits would be missing.
Many paths, like ours, also advice the seeker to follow a vegetarian diet.
