There is nothing permanent except change. [Therefore enjoy what good you have while you have it and endure and outlast what bad you can't cure immediately]
HeraclitusWhosoever wishes to know about the world must learn about it in its particular details. Knowledge is not intelligence. In searching for the truth be ready for the unexpected. Change alone is unchanging. The same road goes both up and down. The beginning of a circle is also its end. Not I, but the world says it: all is one. And yet everything comes in season.
