According to Osho, there is no secret to staying happy and married—it's impossible, because marriage legalizes love and cages a living, unpredictable flow out of fear. Happiness comes by dropping the urge to secure tomorrow, living utterly in the present, and letting love be free—even if it changes or ends. In short: abandon the institution (or its possessiveness) and relate in awareness, not law, promise, or security.
You can’t keep love happy by locking it up; be together freely now without trying to control tomorrow.
