Meditation is the whole science of bringing more and more consciousness out of darkness. The only way is to be as conscious as possible twenty-four hours a day. Sitting, sit consciously, not like a mechanical robot; walking, walk consciously, alert to each movement; listening, listen more and more consciously, so that each word comes to you in its crystal clear purity, its definitiveness. While listening, be silent, so that your consciousness is not covered by thoughts.
Just this moment, if you are silent and conscious you can hear small insects singing their song in the trees. The darkness is not empty, the night has its own song; but if you are full of thoughts then you cannot listen to the insects. This is just an example.
If you become more and more silent, you may start listening to your own heartbeat, you may start listening to the flow of your own blood, because blood is continuously flowing all through your body.
If you are conscious and silent, more and more clarity, creativity, intelligence, will be discovered.
