You can keep as many attachments as you want, but for each attachment you pay a price in lost happiness. Think of it this way: The nature of attachments is such that, even if you satisfy many of them in the course of a single day, the one attachment that was not satisfied will prey upon your mind and make you unhappy. There is no way to win the battle of attachments, yet you have been trained to blame yourself and to be blind to your unhappiness as a result of your cultural and inherited programming.
