As I’ve let my inner hippie free, I’ve caught myself, say, doing yoga and nodding when the teacher says this will help the solar plexus chakra–which is then followed by the thought, “Carl Sagan would not approve of this.”

However, this is Carl Sagan we’re talking about. This is the man who contributed an essay to Marihuana Reconsidered, who approved that theme music* to the Cosmos series, and who famously said:
Some part of our being knows this is where we came from. We long to return. And we can. Because the cosmos is also within us. We’re made of star-stuff. We are a way for the cosmos to know itself.

That last line is what makes me think Carl would be all for letting the inner hippie out.

*Sometimes I just leave that site open and let the music loop. It’s great for irritating days at work.
