In esoteric literature, Sandalphon is usually called an archangel, though some traditions refer to him as an ascended master, or as an angel.
Sandalphon has lived as a man before he ascended.
His aura is believed to be turquoise in colour. Turquoise can be used to tune in to his frequencies.
Sandalphon stands for gentleness, prophecy, healing, manifestation, integrity, and truth. He is referred to as the angel of music, and to one to deliver and answer prayers (the middle-man).
