It depends upon (1) a certain thing I shall not here name; (2) the stage of development to which the chela or occultist has attained or is near attaining; (3) the mode of regarding elementals and the Dweller, peculiar to the chela or occultist, to his family and to his nation, or rather to the national and family legends or religion; (4) which form, more or less monstrous or incongruous, would be most frightful and overpowering to him at the critical period. Subject to the above four conditions, the Dweller assumes a form according to the manner in which the chela or occultist _has or has not fulfilled his threefold duties_, and according to the manner in which the sevenfold elements of the Dweller assert themselves upon him. The better he has fulfilled the threefold duties, the less does the Dweller affect him. Of course the form is not necessarily the same for every one. Why did the Dweller appear to Glyndon’s sister, who was not undergoing probation, and why in the same form? Because she was sympathetic and sensitive enough. The principle involved in this case is the same as in obsession. The Dweller might either be but one elemental, or a group or several groups of elementals assuming one collective form. It is one elemental, when the crisis comes at the very commencement of the chela’s or occultist’s attempt to elevate his lower nature. This is the case when he has the least (Karmic) stamina for the “uphill path.” The later on his path is waylaid the more numerous are the elementals of which the Dweller is composed. It need not be imagined that this appearance or influence confronts the chela only once until he reaches the first initiation, and an initiate only once during the interval between two initiations. It appears as often as the stock of his Karmic stamina falls below the minimum limit. By Karmic stamina is meant the _phala_ (effect or fruit) of past unselfish, good Karma that has become ripened. Though the occultist might have an immense quantity of past unselfish good Karma stored up, still, if during his crisis there be not a sufficient number of present unselfish good thoughts to ripen a sufficient portion of that quantity, he finds himself destitute of the necessary stock of stamina. Few are they who have already laid up a good quantity of unselfish good Karma; and fewer still are they who have the requisite degree of unselfish and spiritual nature during the period of trial; and there are still fewer who would not rush for further Yoga development, without having all the requisite means.
