When you awaken in the night and want to get up, the first thing you do is switch on a light. Once you can see clearly, you can do what you wish, whereas if you try to move about in the dark, you will bump into furniture, break things and hurt yourself.
And yet you have still not understood the lesson of light in the conduct of your inner life; symbolically speaking, you are moving forward in darkness, and that is why you cannot find your way and keep stumbling into things left and right.
You must seek light, concentrate on it, and value it above all the earth’s treasures.
You must even drink and eat light.
Spare a minute whenever you can to close your eyes and concentrate on this image of light that permeates the whole universe and brings all blessings.
