善男子，一切众生从无始际，由有种种恩爱贪欲，故有轮回，若诸世界一切种性，卵生、胎生、湿生、化生，皆因淫欲而正性命，当知轮回，爱为根本，由有诸欲助发爱性，是故能令生死相续，欲因爱生，命因欲有，众生爱命，还依欲本，爱欲为因，爱命为果，由于欲境，起诸违顺，境背爱心而生憎嫉，造种种业，是故复生地狱饿鬼。知欲可厌，爱厌业道，舍恶乐善，复现天人，又知诸爱可厌恶故，弃爱乐舍，还滋爱本，便现有为增上善果，皆轮回故，不成圣道。是故众生欲脱生死，免诸轮回，先断贪欲，及除爱渴。

释迦牟尼

在那样的年纪，我会找任何借口做些估测或者小算术。我会计算油耗还有杂货花销等鸡毛蒜皮的小事。我听过一个有关吸烟的广告。我记不得细节了，但是广告大意是说，每吸一口香烟会减少几分钟的寿命，大概是两分钟。无论如何，我决定为祖母做个算术。我估测了祖母每天要吸几支香烟，每支香烟要吸几口等等，然后心满意足地得出了一个合理的数字。接着，我捅了捅坐在前面的祖母的头，又拍了拍她的肩膀，然后骄傲地宣称，"每天吸两分钟的烟，你就少活九年！"

At that age， I'd take any excuse to make estimates and do minor arithmetic. I'd calculate our gas mileage -- figure out useless statistics on things like grocery spending. I'd been hearing an ad campaign about smoking. I can't remember the details， but basically the ad said， every puff of a cigarette takes some number of minutes off of your life: I think it might have been two minutes per puff. At any rate， I decided to do the math for my grandmother. I estimated the number of cigarettes per days， estimated the number of puffs per cigarette and so on. When I was satisfied that I'd come up with a reasonable number， I poked my head into the front of the car， tapped my grandmother on the shoulder， and proudly proclaimed， "At two minutes per puff， you've taken nine years off your life！"
