Meditation is the most important work to enlightenment.
Meditation consists of the activity of internalizing your thought in order to deconcentrate your mind from what you are used to, with the sights, sounds and sensations of the external world, from day to day. With practice, greater self-knowledge and control of body and mind is sought.
