How does Sayadaw suggest to approach the spontaneous arising of colours and visualisations during meditation?
A. The colours are seen by the mind, a mental state which must be observed until that mind has disappeared. When you see colours, the consciousness of seeing is an absolute reality which must be realized , you must observe it, “seeing, seeing, seeing”, until that colour has disappeared, then that consciousness of seeing has disappeared. Whatever you have in your mind while you are meditating must be observed until it has disappeared.
