One definition of meditation ~
"To meditate means to become familiar with your positive thoughts, positive mind. You try to increase the positive potentials of the mind and reduce the negative imprints in the mind. If you can’t do that it’s useless to just focus your mind on the breath. It’s meaningless. The main thing is to increase the positive potentials that are in your mindstream. That’s called meditation.
At the beginning you think over and over the various positive thoughts, and gradually the mind gets familiar with them, your mind becomes of that nature; then, you don’t even need to think or give a reason, the thought will rise spontaneously in your mind.
You practice the positive over and over, and when you’re able to eliminate the negative thoughts gradually, then this will cause realizations." ~ H.E. Choden Rinpoche ~
