The first aspect is the knower, the second is the known, and the third is the knowing. In other words they may be called the seer, the seen or that which appears, and the sight. These three are three turnings on the same road, which hide it and divide it into three aspects. Therefore, in the spiritual path this puzzle must be solved as the first and last thing. If the barriers which divide these three aspects are removed, then the mystic realizes one life and not three.
