One of the most popular meditation postures is Siddhasana. The Sanskrit name means "Perfect Pose," because one attains perfection in yoga by meditating in this position. Siddhasana is useful to learn, since it is used as the practice seat for some of the pranayamas and the mudras. The positions of the legs and the hands also contain the body energies by closing the circuits and allowing awakened vital forces to remain in the system during meditation practice.
