Hatha uses asanas (postures), pranayama (control of breath), and relaxation to control the physical body and the subtle life force called prana

Jnana Yoga (knowledge)
This is considered the most difficult path because it required a radical shift in perception, the goal is to seek hidden knowledge in all of us through questioning, meditation, and contemplation.
