To reduce destructive emotions we need to strengthen constructive emotions. For example, to counter anger we cultivate love and compassion.
Dalai LamaThere is nothing that does not get easier through cultivation. The buddhas of the past started out as ordinary beings. They were not buddhas in the beginning. The path to buddhahood is traversed only through gradually developing more and more courage and DETERMINATION -then it is attained.
