Be mindful of both actual and potential fragility in yourself and others.
Could it crack?
The truth of anything is like a mosaic with many tiles, many parts.
One part of the truth of things is that they are robust and enduring, whether it's El Capitan in Yosemite or the love of a child for her mother and father.
Another part of the truth is that things bruise, tear, erode, disperse, or end—fundamentally, they're fragile. Speaking of El Capitan, I knew of someone climbing it who had just placed anchors above a long horizontal crack when the sheet of granite he was standing on broke off to fall like a thousand-ton pancake to the valley floor below (he lived, clutching his anchors). Love and other feelings often change in a family. Bodies get ill, age, and die. Milk spills, glasses break, people mistreat you, good feelings fade. One's sense of calm or worth is easily disturbed. Wars start and then end badly. Planets heat up and hurricanes flood cities. Earthquakes cause tidal waves and damage nuclear reactors.
