In purification the self expands to contain the Real. He has rolled up the cosmos in its turn and obliterated it. He has gone beyond. Now perhaps these words can be seen in their true perspective. And he is one of those who not only have clear authority to impart what they know but are obliged to convey their knowledge in order to guide to other human beings to the path of Allah.
Gnosis is the knowledge on which all other knowledge rests.
All knowledges are suppositional yet verifiable in the realm of contingency. This knowledge is real yet not demonstrable. Other knowledges do not, however, illuminate their knower, nor remove his anguish, nor give him judgement in every case, nor invest his presence with light and radiance. The man of knowledge remains in needs and creational dependence. The man of gnosis does not remain in any need except dependency on his Lord who gives him what he requires from creation.
