Zahir - someone or something which, once we have come in contact with them or it, gradually occupies our every thought, until we can think of nothing else. This can be considered either a state of holiness or madness.

                            - Faubourg Saint - Pères

What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness,  and go after that which is lost, until he find it?

                      Luke 15:4 , quoted in 'The Zahir'
