The most important thing in life is the opening of that clear vision which is opened by the help of insight. The effect of every emotion covers the insight, just as clouds cover the sun. It is therefore that most clever and qualified people often do things, especially at the moment of passion or anger, which they would not have done otherwise. The reason is that the mind loses its rhythm under the strain of a passion or emotion, and so it upsets the rhythm of the body, it makes man perplexed and unable to see any condition or situation clearly.
