But you must not change one thing, one pebble, one grain of sand, until you know what good and evil will follow on that act. The world is in balance, in Equilibrium. A wizard's power of Changing and Summoning can shake the balance of the world. It is dangerous, that power...It must follow knowledge, and serve need.
Ursula K. Le GuinLight is the left hand of darkness and darkness the right hand of light. Two are one, life and death, lying together like lovers in kemmer, like hands joined together, like the end and the way.
Ursula K. Le GuinThe menopause is probably the least glamorous topic imaginable; and this is interesting, because it is one of the very few topics to which cling some shreds and remnants of taboo. A serious mention of menopause is usually met with uneasy silence; a sneering reference to it is usually met with relieved sniggers. Both the silence and the sniggering are pretty sure indications of taboo.
