Plunging into the ocean of infinite love

What is eternal life? This is how Benedict XVI depicts it in his new encyclical on Hope:

It would be like plunging into the ocean of infinite love, a moment in which time—the before and after—no longer exists. We can only attempt to grasp the idea that such a moment is life in the full sense, a plunging ever anew into the vastness of being, in which we are simply overwhelmed with joy.
