The Inner Development of Man

If self-development is sought for in this area, then part of it comes about through obedience to and observation of a great sum of rules and directions. Here I could only sketch in sweeping lines how something like this comes about and is experienced. These individual rules must be followed diligently, just like the chemist must weigh and measure with the most delicate instruments the minutest substances needed for a chemical compound. A description of the rules that can be made public will be found in my book, Knowledge of the Higher Worlds and Its Attainment. These rules offer specific instructions for treading this path. They, too, require most diligent patience and perseverance.
