at present your abundance can help those in need; so that when you are in need, their abundance can help you — thus there is reciprocity.
This applies to money, goods, time and work. We may not all be able to give a lot, but what some of us have is more than some will ever see in one place. Even if your surplus isn’t much to you, it can make a world of difference to someone else. Give what you can and expect nothing back.
