In the paperback edition of how to know higher worlds this chapter has 22 numbered paragraphs. I have summarized the first five paragraphs but it is imperitive for you to read the whole text as there are many hidden nuances in the words.

                      Initiation is the highest level of esoteric training.

                     having worked our way through preparation, illumination and initiation and reached the lower mysteries we find that it is not simple to communicate what lies beyond the wall of initiation.

                    Initiation accelerates our spiritual growth , so much so that we might experience what we would otherwise only have experienced in future incarnations.

    we will find obstacles on this path and trials.

                  the mysteries of existence will only be revealed if we are ready for them.

                        the first trial is the fire trial. it is as if a veil is burned away and ones organs of perception are heightened.
