When fear, other emotions, and attachments creep into the mind, it automatically becomes weak. A weak mind looks for reasons to blame our sorrows, difficulties, and problems on. A weak mind loses clarity on why we are acting and what it is we want. A weak mind uses wise quotes or scriptures to justify its weakness. This is why we can relate to Arjuna. And when emotions get the better of us this way, it is sometimes better to watch the movement of the mind as a wave and simply let it pass.
