I like neptune's meaning as well. "The upward crescent for the first time since Mercury turns our attention
toward the superconscious and works to link it with material realities. ... When in balance, Neptune does indeed give one the ability to make dreams come true. This, however, requires patience, unswerving commitment, and willingness to make sacrifices. Impressions and inspiration are put into action to create artistic forms or inventions (particularly when Neptune is assisted by other planetary energies). Another glyph used in Europe shows the circle in place of the cross, emphasizing the more dynamic aspect of Neptune and its association with the process of visualization and active imagery and creation.
