Insanity is nothing but all your suppressions coming to a point where you cannot control them anymore. Meditation is the only way to make you absolutely sane.
Sometimes, we give up all our powers and visions in return for being accepted by the very same forces that imprison us. It is essential to find a way to release whatever tensions and stresses might be building up inside us: Excercise, screaming out in the open or even jumping up and down can do. Anything that shakes us up and helps our energy to circulate freely. Then, sit quietly and meditate.
