I could justify violence only in this extreme case, to save the last living knowledge of Buddhism itself.

In our concern for others, we worry less about ourselves. When we worry less about ourselves an experience of our own suffering is less intense. What does this tell us? Firstly, because our every action has a universal dimension, a potential impact on others' happiness, ethics are necessary as a means to ensure that we do not harm others. Secondly, it tells us that genuine happiness consists in those spiritual qualities of love, compassion, patience, tolerance and forgiveness and so on. For it is these which provide both for our happiness and others' happiness.

To seek solitude like a wild animal. That is my only ambition.

It does not matter whether you are a theist or atheist, what matters is sincerity, forgiveness, and compassion.

If your mental attitude is positive, even when threats abound, you won’t lose your inner peace. On the other hand, if your mind is negative, marked by fear, suspicion and feelings of helplessness, even among your best friends, in a pleasant atmosphere and comfortable surroundings, you won’t be happy.

Of course, there are different truths on different levels. Things are true relative to other things; "long" and "short" relate to each other, "high" and "low," and so on. But is there any absolute truth? Something self-sufficient, independently true in itself? I don't think so.

Warm-heartedne ss and concern for others’ well-being are a condition for happiness, whether you are religious or not.
