On attachment and detachment:
'Being detached does not mean that we cannot enjoy anything or enjoy being with anyone. Rather, it refers to the fact that clinging very strongly to anything or anyone causes us problems. We become dependent on that object or person and think, "If I lose it or cannot always have it, I am going to be miserable."'
'When we help others, we can do it out of attachment or detachment. Helping someone out of attachment would be, for example, "I will help you because I want you to love me. I want to feel needed." We would say that this action of helping is still positive, but the motivation is not the best.'
'Our compassion and generosity must be coupled with discrimination and wisdom.'
