Just close your doors, make the room dark and light a small candle. Sit near the candle with a very loving attitude — rather, with a prayerful attitude. Just pray to the candle, “Reveal yourself to me.” Take a bath, throw cold water on your eyes, then sit in a very prayerful mood before the candle. Look at it and forget everything else. Just look at the small candle — the flame and the candle. Go on looking at it. After five minutes you will feel that many things are changing in the candle. They are not changing in the candle, remember; your eyes are changing.
With a loving attitude, with the whole world closed out, with total concentration, with a feeling heart, just go on looking at the candle and the flame. Then you will discover new colors around the flame, new shades which you were never aware were there. They are there; the whole rainbow is there. Wherever light is, the rainbow is there because light is all color. You need a subtle sensitivity. Just feel it and go on looking at it. Even if tears start flowing, go on looking at it. Those tears will help your eyes to be more fresh.
Sometimes you may feel that the flame, the candle, has become mysterious. It is not the ordinary candle you brought with you; it has taken on a new glamor, a subtle divineness has come into it. Go on doing this. You can also do this with many other things…
