The appoint "Propitious Be" came from the Gardnerian traditions, of the fivefold kiss which is part of the ritual among priest and priestess.
Propitious be thy feet, which go through brought thee in these ways,
Propitious be thy round, that shall bow to at the sacred altar,
Propitious be thy womb, without which we would not be,
Propitious be thy breasts, formed in beauty,
Propitious be thy lips, that shall absolute the Dutiful Names of the gods.
You commonly find pagans and Wiccans parallel use the turn of phrase as a appoint of hand-outs, wishing you good blessings in your life.
