If we wish to bring peace to the world, we must start by changing our evil ways. World peace stems from inner peace. Our goal in studying the Buddha's teachings and cultivation is to attain complete understanding of life and the universe. Be considerate and kind in your speech. To put down another person is only proving your own arrogance and lack of self-confidence to others.
Life is short and fragile.
Practicing virtue is to keep a kind heart, speak kind words, and do kind acts to benefit others. Wise persons do not harbor feelings of gain or loss. In this way, they constantly dwell in the joy of possessing great peace of mind. The point of practicing giving and charity is to forsake greed, hatred, ignorance, and arrogance. When helping others, we should think about benefiting the entire society or even the world instead of limiting our help to just the ones we love.
