Spiritual knowledge can be acquired by the illiterate, who are often more adept at attaining it than those who, seduced by their intellectual capabilities, become mired in the realm of pseudo-knowledge; spiritual knowledge reveals itself to all who, with the fear of God and by the practicing of the commandments in a life of asceticism, have attained purity, simplicity, and humility of heart. Moreover, there is a very close link between true knowledge/contemplation and humility, whereas on the contrary, pseudo-knowledge seems to be linked to pride, whence it proceeds and which it increases.
