Kāmaloka

Kāmaloka is a compound Sanskrit word from kāma (काम), "desire" and loka (लोक), "place". H. P. Blavatsky defined it as follows:

Kamaloka (Sk.). The semi-material plane, to us subjective and invisible, where the disembodied “personalities”, the astral forms, called Kamarupa remain, until they fade out from it by the complete exhaustion of the effects of the mental impulses that created these eidolons of human and animal passions and desires; (See “Kamarupa”.) It is the Hades of the ancient Greeks and the Amenti of the Egyptians, the land of Silent Shadows; a division of the first group of the Trailôkya. (See “Kamadhâtu”.)

Kāmaloka is the stage that precedes the one of devachan (or avitchi in the case of a wicked personality):

From Kama-Loka, then, in the great Chiliocosm, once awakened from their post-mortem torpor the newly translated “Souls” go all (but the shells) according to their attractions, either to Devachan or Avitchi.
