(Rububiyya). The cosmos has two basic levels which are expressed in various ways - that of the Real and the creation, Independence and poverty, Lordship and slavehood. It is the existence of Lordship which demands slavehood. Lordship is the most exalted level and slavehood is the lowest level. There is nothing more lowly than to be subject to the locus of nothingness and to stand in need of another for one's own existence.
