The mind does have the capacity to doubt divine Light afterwards. First you see the Light and at that time the mind is divine. Then, after twelve hours or even five minutes, the mind will gather strength and try to throw suspicion into your experience of Light. When your consciousness descends, when the Light goes away from your physical awareness, at that time you can doubt the Light that you saw. If right now God stands before you, you are not going to doubt Him. But the moment God disappears from your outer vision, you can doubt God.
Because of your oneness with your body, you don't doubt your eyes, you don't doubt your nose. You know that you are part and parcel of your body and that your body is part and parcel of your life; so you don't doubt. Similarly, divine Light is your real existence. How can you deny or doubt your own existence? But after the experience is over, when you do not feel the Light as your own, at that time the mind may throw suspicion and doubt into you.From:Sri Chinmoy,Aspiration and God's Hour, Agni Press, 1977
