In the world, what you have is different from what you are. The ego teaches that what you are is lacking, empty (see lack). To be happy, then, you must apparently have more. You must acquire things from the outside and make sure you do not give them away. In Heaven, however, having and being are the same. What you have is what you are, and what you are is everything. Therefore, you can give all you have without losing it because it is not detachable from you, being what you are. You remember this state through giving in this world (see giving/receiving) and through overcoming all doubts about what you are (see "The Lessons of the Holy Spirit," T-6.V, especially V(B).3,8, V(C).5-8).
