Metaphysical meaning of Belteshazzar (mbd)
The name given by the prince of the eunuchs of Nebuchadnezzar, king of Babylon, to Daniel (Dan. 1:7). In olden times it was customary to change one's name when a change took place in one's life, especially when one's personal liberty was concerned.
Meta. Daniel represents spiritual judgment. When this true inner discernment of Spirit is transferred from its native place (Jerusalem, or spiritual consciousness in man) it appears to take on, for the time being, something of the material thought of the sense realm to which it has been removed. At least this outer realm of consciousness looks upon the true spiritual Judgment from its own sense vision, and renames it accordingly. Bel (trust in the seeming powers of the outer material world) apparently rules over it. But spiritual judgment is always true to its own source, Spirit, and continues to work and to lay up treasure in secret until such time as it and its own thought people (the Jews) shall be restored to their rightful place of dominion. It also uses its clear vision, whenever it has opportunity, to warn and to serve its sensual environing thoughts and activities, to the upliftment and redemption of the whole man.
