p55 – The mind that cherishes others is the supreme good heart. Keeping such a good heart will result only in happiness for ourself and all those around us

The mind that cherishes others is the supreme good heart. Keeping such a good heart will result only in happiness for ourself and all those around us. This good heart is the very essence of the Mahayana path and the main cause of great compassion, the wish to protect all living beings from fear and suffering. Through improving our great compassion we shall eventually achieve the universal compassion of a Buddha, which actually has the power to protect all living beings from suffering. In this way cherishing others leads us to Buddhahood.
