The uniqueness and being original are two opposite things: the former comes from within (is internally driven), the latter - from without (is externally imposed).

The idea (or challange, if you insist) of the uni-corn, or Aquarius, is to combine these two (the higher water and the lower water, as the Aquarius zodiac symbol denotes). From this dualism rises a new consciousness: of co-creativity, within the community.

Two planets related to Aquarius are Saturn and Uranus, a very interesting pair: they are mostly related to advancing in consciousness and awareness, and have a lot to do with life and death (apart from the Scorpio subjects), or spirit and fair judgement.

What are the planets related to Immortality?

Saturn is the master - a gateway or judgement, a wiseman. Uranus is the new consciousness-born - an infant.

Together, the Saturn and Uranus pair with their opposite pair (Sun and Moon) are the keys to attaining immortality: with the "legs" put in (connected to) yin / black color, and "head" put in (connected to) yang / white color. These four found then the vertical part of the world.

Because they are the (gate-)way - tao - they might be symbolized by the black and white horses. "Way" means to move, and you will find no faster energy in the solar system than the one coming from the lightning-fast Uranus energy. Combining both opposite energies: the black one and the white one - leads (is the way) to the ultimate achievement.
