A mystic saint of India, St Brahmanand, has beautifully described the four aspects of the spiritual experience in one of his hymns:
“O saints! I have seen a great miracle. I have seen a bell, a conch and a drum creating music without being played. A deaf man hears this sound and, in ecstasy, totally forgets himself.
'A blind man sees light where there is no sun and there is a palace, without foundations, shimmering with Light. The wonder is that a blind man relates everything in detail.
'There is a well of Nectar in the middle of the sky. A lame man climbs there without a ladder and drinks that ever-flowing Nectar to his heart's content.
