Dr. Davis: May I ask you a question about the role of candles and burning incense?Sri Chinmoy: Each thing has a spiritual significance. Incense gives us purity, and the flame of the candle represents our intense inner cry. Like the flame of the candle, our aspiration or inner cry is going up high, higher, highest. Our inner flame is going up to reach the all-illumining inner sun and then it is entering into the sun and becoming one with it. So definitely you should use a candle when you meditate. When you look at the flame, feel that it is burning in the heart, not in the mind.
