Zarathustra 琐罗亚斯德 (628?—551?BC,古代波斯琐罗亚斯德教创始人)
Love is of three varieties: unselfish, mutual,and ordinary or selfish. Unselfish love is of the highest kind. Here, the one who loves,seeks only the welfare of the beloved and does not care whether he suffers pains and hardships thereby. The second kind of love is mutual love in which the one who loves desires not only the happiness of his beloved, but has an eye to his own happiness also. Selfish love is the lowest. It makes a man care only for his own happiness without having any regard for the feelings of the beloved.
爱有三种:无私的爱、相互的爱、和普通的,即自私的爱。无私的爱是最高境界的爱。 怀着这种爱的人,仅仅谋求他所爱的人的幸福,却不在乎自己是否承受着痛苦和磨难。第二种爱是相互给予的爱,怀着这种爱的人在追求所爱之人幸福的同时,也关注自己的幸福。而自私的爱是最低级的。它使一个人无视他所爱的人的感受而只着眼于自己的快乐。
