Indeed, one can discover a certain happiness working towards a finer comprehension of this, our universe in all its complexity and dimensionality. Coming to know more can make one less afraid. Such an understanding can lead to a benefit in how we choose to live, how we respond to the challenges that arise. But there's another trick in this package. There's accepting and there's accepting.
Some acceptance can seem almost a capitulation.
Look around, being smart is better. No, I'm not talking about the smart-aleck nor the fellow full of hubris. I'm talking about becoming more intelligent about our universe, both the psyche side and the cosmic side. If we better understood how things work, we might not have to cope with so much frustration and aggression that we well know can readily magnify from the individual to the collective. The universe, this Great Matrix, is all we have.
