There are many diverse religions, cultures, histories, and civilizations but all of us live under one sun and moon and on one earth, and we breathe the same oxygen, so we are like one family. We must feel the suffering and happiness of others: we carry all the suffering together and share the happiness. There is a famous quote: If I have happiness, may it be shared by everyone; if others have suffering, may I carry it all.
