The Lotus Pose is said to have been routinely used by Buddha and is a popular meditation pose. It may be uncomfortable at first until your ligaments extend. It's a common misconception that meditation should be done in the Lotus Pose, so if it is too difficult, any other seated pose will work well. This is one of the basic yoga postures, so take your time becoming comfortable in it.
How to do it
Bring your right foot onto your left thigh. Bounce the right knee and, if it touches the floor with ease, bend your left knee and grab your left foot with both hands and place it on your right thigh. Your hands should rest on your knees, either open or forming a mudra.
