When you keep thinking about sense objects, attachment comes. Attachment breeds desire, the lust of possession that burns to anger. Anger clouds the judgment; you can no longer learn from past mistakes. Lost is the power to choose between what is wise and what is unwise, and your life is utter waste. But when you move amidst the world of sense, free from attachment/craving (raga) and aversion (dvesha) alike, there comes peace in which all sorrows end, and you live in the wisdom of the Self.
