Source: Webster's dictionaryA person cries out against life because it's lonely, and because life's broken off from whatever created it. But no matter how much you hate life, you love it, too. It's like a caldron boiling with everything you have to have - but very painful to the lips. Frank Herbert
As a sunbeam quivers upon the walls of a house when flung up from water, which is just poured forth in a caldron or a pail may be; and hither and thither on the swift eddy does it dart and dance along. Apollonius of Rhodes
