The next and still greater mystery of the cross can be observed in the life of the messengers, the prophets, the holy beings. In the first place no one has entrance into the kingdom of God who has not been so crucified. There is a poem by the great Persian poet Iraqi, who tells us how he went to the gate of the Beloved and knocked at the door; and a voice answered, 'There is no place for anyone else in this abode. Go back to where you came from', and he went back. Then, after a long time, and after having gone through the process of bearing the cross and being crucified, he came again, this time full of that spirit of selflessness, and he knocked at the door and the word came, 'Who art thou?' and he said, 'Thyself alone, for no one else exists save thee. ' And God said, 'Enter into this abode for now it belongs to thee.'
