The disciples of Christ learnt what no study or practice would have ever taught them, namely, by His presence. In the time of Mahomet Ali Mooman, his disciples, being in his presence, gained very great benefit from his presence. There then comes a time when the external presence is not needed. After having travelled along this path, the inner presence of the master, the teacher, will inspire. Strictly speaking, then we learn by contact with, or association with a teacher what words cannot teach, what study will not bring, and, even practices cannot help. That is what the path of discipleship is.
