People who have had deep experiences of any kind, of suffering, of agony, of love, of hate, of solitude, of association, of success, of failure, all have a particular quality, a quality which has a special use for others. And when a person realizes this, he will come to the conclusion that whatever has been his life’s destiny, his heart has prepared a chemical substance through sorrow and pain, through joy or through pleasure, a chemical substance that is intended for a certain purpose, for the use of humanity, and that he can only give it out if he can keep his heart awakened and open…It does not matter what he has gone through, for even the worst poison can be of some use. There is no person, however wicked, who is of no use, if only he realizes that the first condition for being useful to humanity is to keep his heart open.
HIK The Heart Quality Vol VIII p 266
