" It is a weakness to think that any one is dependent on me, and that I can do good to another. This belief is the mother of all our attachment, and through this attachment comes all our pain. We must inform our minds that no one in this universe depends upon us; not one beggar depends on our charity; not one soul on our kindness; not one living thing on our help. All are helped on by nature, and will be so helped even though millions of us were not here. The course of nature will not stop for such as you and me; it is, as already pointed out, only a blessed privilege to you and to me that we are allowed, in the way of helping others, to educate ourselves. This is a great lesson to learn in life, and when we have learned it fully, we shall never be unhappy; we can go and mix without harm in society anywhere and everywhere. "
