“Meditation is a state, often defined as deep dreamless sleep awake. But, in the same way that you cannot sleep on demand, you cannot meditate on demand—that is, you can’t reach the state instantly in the same way that you can raise your right hand. The practices preceding meditation are relaxation, stillness and mental focus. Those are all things you can do. They are the preparation. Then, if you the circumstances are right, you can transition from the waking to the meditative state.”
