Tension
Intimacy is not a happy medium. It is a way of being in which the tension between distance and closeness is dissolved and a new horizon appears. Intimacy is beyond fear.
From the beginnings of literature, poets and writers have based their narratives on crossing borders, on wandering, on exile, on encounters beyond the familiar. The stranger is an archetype in epic poetry, in novels. The tension between alienation and assimilation has always been a basic theme.
There's a constant tension between the excitement of new people and security with one person. If you go with excitement, you create chaos; you hurt people. There's jealousy, and it gets very messy. If you have security, it can be boring, and you die inside because of all the opportunities missed.
If you ask what is the single most important key to longevity, I would have to say it is avoiding worry, stress and tension. And if you didn't ask me, I'd still have to say it.
The philosophy of life is this: Life is not a struggle, not a tension... Life is bliss. It is eternal wisdom, eternal existence.
