Rajyoga usually refers to the system of yoga that is described in the Yoga
Sutras of Sage Patanjali. In this ancient text Sage Patanjali describes
eight stages of yoga which are known collectively as Rajyoga.
Rajyoga is a comprehensive yoga system which deals with the refinement
of human behaviour and personality through the practice of the yamas
(restraint) and niyamas (disciplines); attainment of physical health
and vitality through asanas (postures) and pranayamas (pranic breathing
techniques); management of mental and emotional conflicts and development
of awareness and concentration through pratyahara (sensory withdrawal)
and dharana (concentration); and developing the creative aspect of consciousness
for transcendental awareness through dhyana (meditation) and samadhi
(absorption in the universal identity).
