The Dweller.

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.
