In fact, anything great, is difficult, cheap things come easily. If you want a cheap relationship, then everything will be easy. But when it becomes difficult, then the relationship is broken. But if we really want our relationship to have deep substance, deep meaning and deep fulfillment, difficulties have to be endured. And how do we do that? From the day of marriage, and throughout our lives, to deeply within our hearts, accept that our relationship is based on a higher principle than either of us. Because the nature of the mind is sometimes, we like each other and sometimes we don't like each other; sometimes we're happy, sometimes we're angry.
