By the time the Bodhisattva gives up everything he/she has realized things, all things are empty of any thing that brings lasting happiness. It is easy for them to walk the path of enlightenment so they can help others find relief from the suffering of grasping at things as me or mine..

You know things, even our body is made up of bits and pieces of other things, and these things are made up of other things. All beings and worlds are made up of tiny bits of this and that... There is no self in the flux of things, they are constantly shifting and changing...but there is what is not a thing and that is the aim of the teaching to stop grasping at things and see without our eyes what is not a thing ...hahaha
