As it is with prayer...

When you love someone, you do not love them all the time, in exactly the same way, from moment to moment. It is an impossibility. It is even a lie to pretend to. And yet, this is exactly what most of us demand. We have so little faith in the ebb and flow of life, of love, of relationships. We leap at the flow of time and resist in terror its ebb. We are afraid it will never return. We insist on permanency, on duration, on continuity; when the only continuity possible in life, as in love, is in growth, in fluidity – in freedom.

The only real security is not in owning or possessing, not in demanding or expecting, not in hoping, even. Security in a relationship lies neither in looking back to what it was, nor forward to what it might be, but living in the present and accepting it as it is now. For relationships, too, must be like islands. One must accept them for what they are here and now, within their limits – islands surrounded and interrupted by the sea, continuously visited and abandoned by the tides. One must accept the serenity of the winged life, of ebb and flow, of intermittency.
