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, as it is used as the practice seat for some pranayamas and mudras. The positions of the legs and hands also help contain the body's energies by closing circuits, allowing awakened vital forces to remain in the system during meditation practice.
