Dhyana or meditation in yoga is the 7th stage or step in the eight-limbed Ashtanga Yoga. Dhyana is explained in the Yoga Sutras of Maharishi Patanjali as constant and effortless flow of awareness a point, object or a centre. Dhyana leads to Samadhi or the superconscious state (the 8th Stage of Ashtanga Yoga).
Padmasana or the Lotus Pose is an important meditative asana. The yogic texts mentions the importance of this pose. In Sanskrit, Padma means lotus and Asana means pose. Hatha Yoga Pradeepika talks of Padmasana, as one of the main asanas for meditation that can destroy all diseases.
