Eknath Easwaran's Commentary
When the mind gets agitated, we do not see life as it truly is, as one. It is the constant agitation going on in our mind that deludes us into believing that you and I are separate.
The question we may well ask is, “If we are to have neither pleasure nor pain in life, are we not likely to become insensitive to the joy of life?” This doubt arises from a wrong assumption, that there is only pleasure and pain and nothing else. Always cutting things up into two classes – everything must be either this or that – is one of the fatal weaknesses of the intellect. Because of this dualistic trap, we find it difficult to understand that the rare person who is able to receive good fortune without getting excited, and bad fortune without getting depressed, lives in abiding joy.
