the knot that cannot be untied

I'm not sure how it first popped into my mind, but this problem used to vex me as a child. Looking back I realise it was my first koan.

The answer is that there is no knot that cannot be untied.

In other words, all conditioned states are subject to dissolution. Our psyches and bodies will completely unravel; they contain their own distruction.

This world is a dream world, and we are all sleepers living out strange dreams. Each of us creates the world around us, the illusion becoming tighter and more structured, like a knot, until we lose our way back amid the topology.

Our way back to what? The void from when and where we came, which we carry around with us still.

We have black holes at our core, in our hearts, waiting to carry us home.
