Traditionally, there are four paths to attain the highest spiritual goal that is to have union (Yoga) with God or Atman: by devotion (Bhakti Yoga); by the control of body and mind — meditation (Rāja Yoga); by using the faculty of discrimination to hold on to the Eternal and giving up the materialistic changeable world (Jnāna Yoga); and through unselfish work (Karma Yoga).
