To remain indifferent to the challenges we face is indefensible. If the goal is noble, whether or not it is realized within our lifetime is largely irrelevant. What we must do therefore is to strive and persevere and never give up.
When something needs to be done in the world to rectify the wrongs, if one is really concerned with benefiting others, one needs to be engaged, involved. This is action out of compassion.
I am sometimes sad when I hear the personal stories of Tibetan refugees who have been tortured or beaten. Some irritation, some anger comes. But it never lasts long. I always try to think at a deeper level, to find ways to console.
Sometimes we feel that one individual's action is very insignificant. Then we think, of course, that effects should come from channeling or from a unifying movement. But the movement of the society, community or group of people means joining individuals. Society means a collection of individuals, so that initiative must come from individuals. Unless each individual develops a sense of responsibility, the whole community cannot move. So therefore, it is very essential that we should not feel that individual effort is meaningless- you should not feel that way. We should make an effort.
If you develop a pure and sincere motivation, if you are motivated by a wish to help on the basis of kindness, compassion, and respect, then you can carry on any kind of work, in any field, and function more effectively.
