The aerial spirits are next in importance to the bourkhans; some of them are beneficent, others malignant. The Kalmucks worship these rather than the others, because they alone can do harm to mortals, whilst nothing but good offices are to be expected from the beneficent spirits. These genii are not immortal, and their power is much less than that of the bourkhans. The manner in which their race is propagated is very simple, but singular: an embrace, an exchange of smiles, or of gracious looks is sufficient with them to produce conception. All these spirits have divers abodes in the world and in the air; to the malevolent among them, the Kalmucks attribute all the disorders of the atmosphere, and all pestilential diseases; the evil genii are particularly active in stormy weather, wherefore the Kalmucks greatly dread thunder, and always fire many shots when a storm blows, in order to scare away the demons.
There are also in the Lamite religion a great many fabulous deities represented by monstrous idols, which appear to be old reminiscences of a primitive creed anterior to Buddhism. It is remarkable that these idols have generally female faces. They are almost always decorated with the scarf of honour, or the bell and sceptre, used by the priests in their religious ceremonies, are placed in their hands. The priests are the makers of all these idols, some of which are of curious workmanship. The materials are baked earth, bronze, silver, or even gold.
Though the Kalmucks address their worship almost exclusively to the host of secondary deities we have just mentioned, still they acknowledge a supreme being, to whom the bourkhans and the good and evil genii are but vassals: if they have no image or idol representing him, it is because the conception of the one eternal creator passes all the bounds of their imagination, and they rather apply their thoughts to beings less incomprehensible and less remote from their own nature. Pallas seems to think that the Kalmucks follow the system of Epicurus, but the conversations I have had with many learned princes and priests, have convinced me of the contrary.
The Kalmucks and the Mongols believe, like the Hindus, in the transmigration of souls; but Bergmann errs greatly in asserting that they have no other idea of immortality. I have investigated the popular notions on this subject, and my conviction is that the Kalmucks consider the transmigration only as a longer or shorter trial which the soul of every man, not acknowledged a saint, must pass through before appearing in presence of the supreme judge. As for those who have been celebrated for their piety and their virtues, Lamism teaches that they are raised to the rank of bourkhans, still preserving their former individuality.
Erlik Khan is the great judge of the Kalmuck hell, and before his awful throne all souls must appear, to be rewarded according to their works. If they are found just and pure, they are placed on a golden seat supported on a cloud, and so wafted to the abode of the bourkhans; if their sins and their good works seem to balance each other, then Erlik Khan opens his great book in which all the good and evil deeds of men are minutely recorded, and having cast the dread balance, he finally pronounces sentence. On the whole this king of hell seems a good-natured devil enough, for very often to avoid condemning an unfortunate sinner who has some good qualities to recommend him, he allows him to go back to earth and live over again in his own form. The Kalmucks, always logical in their mythological notions, allege that they derive from men thus resuscitated all the knowledge they possess of hell and the future life.
