I tried to find Him on the Christian cross, but He was not there; I went to the Temple of the Hindus and to the old pagodas, but I could not find a trace of Him anywhere. I searched on the mountains and in the valleys but neither in the heights nor in the depths was I able to find Him. I went to the Caaba in Mecca, but He was not there either. I questioned the scholars and philosophers but He was beyond their understanding. I then looked into my heart and it was there where He dwelled that I saw Him; He was nowhere else to be found.
