Nothing in this universe is permanent but our indestructible spirits.
All is in constant flow and flux. What you call a stone is made of minute energy particles coalesced into matter, yet on a deeper level, permeable. On an even deeper level, nothingness.
Somehow, we are in a place where we perceive matter in solid form. Yet the pattern of non-permanence is shown to us in our cycles of life death life. All living things come into being, then must decay and pass away.
All landscapes erode, all cloud formations dissipate, all musical tones die away to the ear, bedrock becomes sand, and yet all deaths give rise to the new.
The upstart cottonwood sprout will surge ahead and surpass me some day as I enter my season of decline. Our parents will pass on, our beloved shade trees will succumb to age, our favorite pets will cease to exist on the physical plane.
