Pop music gives us the clue. Something is wrong with our heart. Even if she loves us truly, forlorn hope since we don’t know who we are, it cannot last forever. In that case, dance!
We want something to last forever so we detach our heart from the body and call it love. The physical world has an analogy for our mad practice: it’s called the obliquity, the tilt of the Earth’s rotational axis to its orbital plane.
The wanting something to last forever is dukkha, the anti-vertex, and the detachment we call universal love is anicca, the vertex.
Twice a day these angles of rotation to revolution coincide with the prime vertical at the horizon, when the solstices are at midheaven. Twice a day we strut the impossibility of eternity, and twice a day you think you’re wise to it.
