A compassionate attitude opens our inner door, and as a result it is much easier to communicate with others. If there is too much self-centered attitude, then fear, doubt and suspicion come and as a result our inner door closes. Then it is very difficult to communicate with others.
Study and practice are both very important, but they must go hand in hand. Faith without knowledge is not sufficient. Faith needs to be supported by reason.

If you resort to violent methods because the other side has destroyed your monastery, for example, you then have lost not only your monastery, but also your special Buddhist practices of detachment, love, and compassion.
Those who suffer from an exaggerated sense of their own ability and accomplishment are continually subject to frustration, disappointment, and rage when reality intrudes and the world doesn't validate their idealized view of themselves.
Every noble work is bound to face problems and obstacles. It is important to check your goal and motivation thoroughly. One should be very truthful, honest, and reasonable. One's actions should be good for others, and for oneself as well. Once a positive goal is chosen, you should decide to pursue it all the way to the end. Even if it is not realized, at least there will be no regret.

Far better, surely, to use our short time here in living a meaningful life, enriched by our sense of connection with others and being of service to them.
