"What are you reading? I am feeling sleepy please switch off the light." A teenager said to me.
"Spiritual reading!" I replied.
"What's that?" He inquired.
I started reading loudly. "Sit silently in a quiet room for one or two hours. Close your eyes and concentrate on the point between the eyebrows. Withdraw the mind and the senses from the external objects. Be still."
"Oh! That!! Our teacher has also told us that if we concentrate our mind then we see different lights. If we see black light it means our concentration is poor. Seeing red colour means our mind is somewhat concentrated. It increases if we see orange colour. On concentrating more we see yellow, green, blue, indigo and violet lights consecutively. Seeing white colour means our mind is concentrated excellently.
Dear readers, which light do you see on concentrating your mind?
