Neptune is the second of the generational planets, spending fourteen years in each sign. Everyone born within that period will have Neptune in the same sign. By itself, this placement is not the most important factor in your chart; however, it symbolizes what was going on in the world at the time you were born, and this has left an imprint on you.
You and members of your generation are each imbued with this particular energy, and in some ways it characterizes everyone born during this time. Each individual will express it in their own way, some more strongly than others. Those with Neptune in Pisces will help to refine and purify the gross materialism that seems to have overtaken the world. You and your peers will revitalize spiritual practices all over the world, and seek to establish healing centers as well as spiritual retreats.
