In these four lectures Annie Besant traces the path of discipleship through percep-tible and subtle milestones. The experi-ence that is gained by action done for self-gratification could be elevated to a dutiful performance of rites and ceremo-nies for the settlement of karmic debts, which in turn could ascend into a joyful sacrifice that accomplishes union with the Divine. Control of mind, meditation, and building of character, qualifies the aspi-rant to receive the revelation of the Teacher. The life of the disciple that was preparatory in a general sense assumes more definite shape on the probationary path. A bird's eye view of the evolution of humanity as a whole, from the past to the future, is also laid before the seeker.
