Feeling is vibration. The heart which is a vehicle, an instrument of feeling, creates a phenomenon, if one only watches life keenly. If one causes anyone pain, that pain returns; if one causes anyone pleasure, that pleasure returns. If you give love to someone, loves comes back, and if you give hatred, that hatred comes back to you in some form or other. Maybe in the form of pain, illness, health, success, joy, or happiness - in some form or other it comes back, it never fails. Generally one does not think about it, and when a person has got a certain position where he can order people about and where he can speak harshly to them, he never thinks about those things. Every little feeling that rises in a man's heart, and directs his action, word and movement, causes a certain reaction and rebounds; only it sometimes takes time. But do not think that you can ever hate a person - even have the slightest thought of it - and that it does not come back; it surely comes back some time. Besides, if you have sympathy, love, affection, a kind feeling for a person, even without telling him so, it returns in some form or other.
