Surges for spiritualism come and go. The sixties was one, but it was by no means the first in America, nor the strongest, (I'd give that one to the Second Great Awakening) but it was very pluralistic, I'll give it that. The spiritual aspect of the CounterCulture (which gave us both Baba Ram Dass and the JesusFreaks) was more about finding a solution and a way that was not science and technology and free market enterprise then it was any specific soul hunger on the part of those who grew up as Sunday Christians.
And I don't even think it was (or is, as I said, its ongoing) about having control over our own communities, it was about the more basic issue of creating community in the first place.
I did the 40th Gathering of the Tribes for the Summer of Love this past summer, and those flower girls (and boys) all have gray hair now, still, many are quite pretty. Many still work in the arts, in schools, in music and in political change, so they have not changed all that much.
