If one is the master of the earth, he is still the slave of Heaven. It is he who is no-one who can be all. The Sufi therefore takes the path of being nothing, instead of being something. It is this feeling of nothingness which turns out of the human heart an empty cup, in which the wine of immortality is poured out. It is this state of bliss which every truth-seeking soul yearns to attain. It is easy to be learned, and it is not very difficult to be wise; and it is within one's reach to become good, and it is not an impossible achievement to be pious or spiritual. But if there is an attainment which is greater and higher than all these things, it is to be nothing.
