"It is hoped that those who read these letters will endeavour to do two things: 1. Read always with an open mind, remembering that the truth is a many-sided diamond, and that its different aspects will appear at different times, as those who guide the race see a need which must be met. Many books on meditation have been written, some too abstruse and some too superficial to satisfy the average educated man. The writer of these letters has apparently attempted to supply the need of a brief yet scientific exposition of a rationale of meditation, emphasising the goal immediately ahead and the intermediate stages. 2. Judge of the letters on their merits and not upon claims put forth on behalf of the writer. For this reason he has chosen to preserve his anonymity and has requested the recipient of the letters to publish them under his pseudonym. If the subject matter of the letters is of value it will call forth a response from the readers and serve to help some onward towards the goal, and prove to many the inspiration and aid it already has to a few.
