Courage is the most important of all the virtues, because without courage you can't practice any other virtue consistently. You can practice any virtue erratically, but nothing consistently without courage.
Happiness of any given life is to be measured, not by its joys and pleasures, but by the extent to which it has been free from suffering-from positive evil.
Ah, how little you know of human happiness - you comfortable and benevolent people! For happiness and unhappiness are brother and sister - or even twins who grow up together - or in your case - remain small together!
It is my observation that all human hearts are the same and that their ultimate desire is also the same. This soul wants happiness, perfect and pure happiness, because only then will all desires end. As long as desire exists misery exists, because with desire there can be no peace.
We begin from the recognition that all beings cherish happiness and do not want suffering. It then becomes both morally wrong and pragmatically unwise to pursue only one's own happiness oblivious to the feelings and aspirations of all others who surround us as members of the same human family. The wiser course is to think of others when pursuing our own happiness.
Happiness arises as a result of different causes and conditions. If you harm someone out of anger, you may feel some superficial satisfaction, but deep down you know it was wrong. Your confidence will be undermined. However, if you have an altruistic attitude, you’ll feel comfortable and confident in the presence of others.
