Why is Neptune known as a "generational planet?":
It takes about 14 years for Neptune to pass through a sign, so those born in a particular period have this in common. It influences a generation and the lens through which that group handles Neptunian concerns.
The long view of history reveals the impact a generation made on the culture via Neptune. One example is the 1960s when Neptune was in Scorpio, and there was heavy experimentation in drugs, and the music veered toward the trance-like, shadowy, dark, mysterious and subterranean. Neptune shapes the collective myths, and the memory of that era is colored by Scorpionic undertones of emotional intensity.
Neptune was named for the Roman god of the sea, and its province is the oceanic depth of the imagination, dreams and spiritual visions. Our nightly dreams can be a portal through which we find meaning in life. And dreams, as well as the visions of waking life, can be expressed through art, dance, movies, music, etc, reflecting back to us a vision of that inner world.
Neptune is a bridge to the mysterious and that knowing many of us have that we’re all somehow linked. It's like the other slow moving planets. guiding each generation toward its collective spiritual destiny. Because of this, it’s often easier to see how it colored a particular period in retrospect.
Beyond the sign shared by an entire generation, the house position of Neptune is important in the individual birth chart. It shows areas of life that could bring up confusion because it’s hard to discern reality from illusions. But it also points to how you'll express the vast landscape of the imagination through creativity. It might show what areas of life you find spiritual meaning, as well.
If Neptune is prominent in your chart – if there are many favorable aspects, for example – you could be naturally drawn toward the spiritual path and mysticism. Neptune also holds sway, if you have a heavy Pisces influence in your chart. But everyone has a personal dream world and the potential for creativity, and the house and sign position shows how this part of life will be expressed.
