Yes, absolutely, being "Indigo" does not make you superior to anyone else, and if you DO feel superior, that's your ego kicking in. (The ego is one of the main obstacles to knowing God.) The way I see it, Indigos are born with a spiritual "head-start", so to speak - ie. they are born higher-vibrational. Anyone can get to that state, they just have to work harder at it than Indigos, who are old souls and are born with much "spiritual intelligence" accumulated over many lifetimes. Hope that makes sense.
