No matter what activity or practice we are pursuing, there isn't anything that isn't made easier through constant familiarity and training. Through training, we can change; we can transform ourselves. Within Buddhist practice there are various methods of trying to sustain a calm mind when some disturbing event happens. Through repeated practice of these methods we can get to the point where some disturbance may occur but the negative effects on our mind remain on the surface, like the waves that may ripple on the surface of an ocean but don't have much effect deep down. And, although my own experience may be very little, I have found this to be true in my own small practice. So, if I receive some tragic news, at that moment I may experience some disturbance within my mind, but it goes very quickly. Or, I may become irritated and develop some anger, but again, it dissipates very quickly. There is no effect on the deeper mind. No hatred. This was achieved through gradual practice; it didn't happen overnight.'Certainly not. The Dalai Lama has been engaged in training his mind since he was four years old.
