There are many more moments of attachment than we ever thought. one may think that attachment arises only when one wants to possess things, when one is greedy. But there are many forms of attachment, some of which are gross and some more subtle. Isn't there very often, after we have seen something, like of what we have seen? Do we not cling to seeing or to our eyes? We would not want to part with an eye or lose the ability to see. That shows that there is attachment. There is bound to be attachment after we have seen, heard, smelt, tasted, experienced objects through the bodysense and also when experience objects through the 'mind-door'.
