Marriage was contrived for ordinary people, for people who are capable of neither great love nor great friendship, which is to say, for most people--but also for those exceptionally rare ones who are capable of love as well as of friendship.
In Tibet there is no marriage, and there is no jealousy, yet we know that marriage is a much higher state. The Tibetans have not known the wonderful enjoyment, the blessing of chastity, the happiness of having a chaste, virtuous wife, or a chaste, virtuous husband. These people cannot feel that. And similarly they do not feel the intense jealousy of the chaste wife or husband, or the misery caused by unfaithfulness on either side, with all the heart-burnings and sorrows which believers in chastity experience. On one side, the latter gain happiness, but on the other, they suffer misery too.
The natural ambition of woman is through marriage to climb up, leaning upon a man; but those days are gone. You shall be great without the help of any man, just as you are.
