Bhagavad Gita, Chapter 2 verse 62: From pondering on objects of the senses, attachment. From attachment, desire. From desire arises anger.
Anger arises from our inability to fulfill desire for happiness and contentment in material objects of the senses. 'From pondering on objects of the senses' one becomes attached to the object's attractive qualities. ‘From attachment, desire’ to acquire the object through action — hence the endless cycle of impression-desire-action (2.39). But happiness and contentment lie within, not in an object's attractive qualities. Disappointment in the object's inability to provide fulfilling contentment (2.46) frustrates the mind and ‘gives rise to anger.’
