“…the Valley of Astonishment and Bewilderment, where one is a prey to sadness and dejection. There sighs are like swords, and each breath a bitter sigh; there, is sorrow and lamentation, and a burning eagerness. It is at once day and night. There, is fire, yet a man is depressed and despondent. How, in his bewilderment, shall he continue his way? But he who has achieved unity forgets all and forgets himself. If he is asked: ‘Are you, or are you not? Have you or have you not the feeling of existence? Are you in the middle or on the border? Are you mortal or immortal?’ he will reply with certainty: ‘I know nothing, I understand nothing, I am unaware of myself. I am in love, but with whom I do not know. My heart is at the same time both full and empty of love.’ “
– Farid ud-Din Attar, (English translation by C. S. Nott)
