Marriage is a fierce battle before which the two partners ask heaven for its blessing, because loving each other is the most audacious of enterprises; the battle is not slow to start, and victory, that is to say freedom, goes to the cleverest.
Your most vital necessity in this life is that you shall love your wife completely and implicitly and in an entire nakedness of body and spirit.... this that I tell you is my message as far as I've got any.
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 ideal that marriage aims at is that of spiritual union through the physical. The human love that it incarnates is intended to serve as a stepping stone to diving or universal love.
