According the original book published to put this together,
The Indigo Children: The New Kids Have Arrived, Lee Carroll and Jan Tober, they interviewed the woman who first brought this to light. Her name is Nancy Ann Tappe. Tappe wrote a book called
Understanding Your Life Through Color, and she had noticed that after a certain year, people were no longer being born with some of the life colors, and there were more and more people being born with a new color. That new color, according to her, is indigo.
She also claims, past a certain year, all the children are being born indigo.
In both times I have read the book, I have found the book not to be very insightful. Much of it relates more to parents feeling very special about their children, or how to "deal" with indigo kids, rather than dealing with themselves.
I think James Twyman's
Emissary of Love as a better starting place for finding your life purpose.
Everyone, whether you are "indigo" or not, are expressions of Universe. Twyman had encountered some folk who taught, what would you do
right now if you knew you are an emissary of love? Check it out sometime.
There is one interesting tidbit Tappe had said. She says, each of the life colors comes with a "curriculum", that is, if you see incarnation as a school of sort, learning some particular lesson or experience. She says, indigo kids are not born with a curriculum, and it won't show up until they are 26, 27, and then there's a shift.
Age 28 and 29 is about when you get the first Saturn Return. Based on my experience with mine's, and based on what I've read about it in the psychological / karmic astrology literature, this makes a lot of sense. Your entire first Saturn Return is you "booting up", where Saturn shows you how each of the consciousness radiating from the signs works and manifests in your life. Then when you get your first Saturn Return, Saturn is saying, "Ok. Now it's your turn."
Your chart says you are born in 1994, so you would not have had your first Saturn Return. My suggestion:
(1) Don't worry about whether you are an "indigo" or not. It doesn't matter. Those are labels more to make parents happy than to make you happy. However, I would encourage you to find out more deeply about Indigos in general. There are other prophecies and earth changes that are related to this. There are a
lot of literature, if reading is what you like to do.
(2) If you have not found your purpose yet, that's fine too. What you are doing now is preparing you for what you will be doing. Trust me, you'll look back and be amazed at how things turned out.
(3) I highly recommend starting up a meditative practice. Mindfulness is the fastest way to get to know yourself. You cannot find yourself in books, in forums, or on Google. A good starting primer available for free online is:
