Thanissaro Bhikkhu wrote:Every time you take a choice - at home, at work, at play - you are exercising your power in the on-going fashioning of the world. At the same time, this principle allows you to measure yourself in terms that are entirely under your control: your intentional actions in the present moment. In other words, they don't force you to measure yourself in terms of your looks, strength, brains, financial prowess, or any other criteria that depend less on your present karma than they do on karma from the past. Also, they don't play on feelings of guilt or force you to bemoan your past lapses. Instead, they focus your attention on the ever-present possibility of living up to your standards in the here and now.
