The “Dweller on the Threshold” is found in two cases: (a) In the case of the separation of the Triangle from the Quaternary; (b) When Kâmic desires and passions are so intense that the Kâma Rûpa persists in Kâma Loka beyond the Devachanic period of the Ego, and thus survives the reincarnation of the Devachanic Entity (e.g., when reincarnation occurs within two hundred or three hundred years). The “Dweller” being drawn by affinity towards the Reincarnating Ego to whom it had belonged, and being unable to reach it, fastens on the Kâma of the new personality, and becomes the Dweller on the Threshold, strengthening the Kâmic element and thus lending it a dangerous potency. Some become mad from this cause.
Intellect.
The white Adept is not always at first of powerful intellect. In fact, H. P. B. had known Adepts whose intellectual powers were originally below the average. It is the Adept's purity, his equal love to all, his working with Nature, with Karma, with his “Inner God,” that give him his power. Intellect by itself alone will make the Black Magician. For intellect alone is accompanied with pride and selfishness: it is the intellectual plus the spiritual that raises man. For spirituality prevents pride and vanity.
Metaphysics are the domain of the Higher Manas; whereas [pg 540] Physics are that of Kâma-Manas, which does the thinking in Physical Science and on material things. Kâma-Manas, like every other Principle, is of seven degrees. The Mathematician without spirituality, however great he may be, will not reach Metaphysics; but the Metaphysician will master the highest conceptions of Mathematics, and will apply them, without learning the latter. To a born Metaphysician the Psychic Plane will not be of much account: he will see its errors immediately he enters it, inasmuch as it is not the thing he seeks. With respect to Music and other Arts, they are the children of either the Mânasic or Kâma-Mânasic Principle, proportionately as Soul or technicality predominates.
Karma.
After each incarnation, when the Mânasic Ray returns to its Father, the Ego, some of its atoms remain behind and scatter. These Mânasic atoms, Tânhic and other “causes,” being of the same nature as the Manas, are attracted to it by strong bonds of affinity, and on the reincarnation of the Ego are unerringly attracted to it and constitute its Karma. Until these are all gathered up, the individuality is not free from rebirth. The Higher Manas is responsible for the Ray it sends forth. If the Ray be not soiled, no bad Karma is generated.
The Turîya State.
You should bear in mind that, in becoming Karma-less, good Karma, as well as bad, has to be gotten rid of, and that Nidânas, started towards the acquisition of good Karma, are as binding as those induced in the other direction. For both are Karma.
Yogîs cannot attain the Turîya state unless the Triangle is separated from the Quaternary.
