The world is an echoing place. if we throw anger, anger comes back; if we give love, love comes back.
Love should not be demanding; otherwise it loses wings, it cannot fly. It becomes rooted in the earth becomes very earthly; then it is lust and it brings great misery and great suffering. Love should not be conditional, one should not expect anything out of it. It should be for its own sake -- not for any reward, not for any result. If there is some motive in it, again, your love cannot become the sky. It is confined to the motive; the motive becomes its definition, its boundary. Unmotivated love has no boundary: it is pure elation, exuberance, it is the fragance of the heart.
And just because there is no desire for any result, it does not mean that result do not happen; they do, they happen a thousandfold, because whatever we give to the world comes back, it rebounds. The world is an echoing place. If we throw anger, anger comes back; if we give love, love comes back. But that is a natural phenomenon; one need not think about it. One can trust: It happens on its won. Thisn is the law of karma: whatever you sow, you reap; whatever you give, you receive. So there is no need to think about it, it is automatic. Hate, and you will be hated. Love, and you willbe loved.
