Eknath Easwaran's Commentary
A fast mind is like a race car in the hands of a dubious driver. Fear, resentment, greed, anger, self-will, and jealousy rush through the mind at a hundred miles an hour. At such speeds we cannot turn, stop, or keep from crashing into people. At speeds like this we are not really driving at all. We are hostages, trussed up in the trunk. And who knows who is at the wheel?
The function of passage meditation is twofold: it slows the mind, and by absorbing the words of an inspirational passage deep into consciousness, it gradually transforms negative emotions into positive states of mind. The slower the thoughts go, the greater the control you have over them, and the more positive they become.
