Zarathustra 瑣羅亞斯德 (628?—551?BC,古代波斯瑣羅亞斯德教創始人)
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.
愛有三種:無私的愛、相互的愛、和普通的,即自私的愛。無私的愛是最高境界的愛。 懷著這種愛的人,僅僅謀求他所愛的人的幸福,卻不在乎自己是否承受著痛苦和磨難。第二種愛是相互給予的愛,懷著這種愛的人在追求所愛之人幸福的同時,也關注自己的幸福。而自私的愛是最低級的。它使一個人無視他所愛的人的感受而只著眼于自己的快樂。
