Imagine a limitless expanse of water: above and below, before and behind, right and left, everywhere there is water. In that water is placed a jar filled with water. There is water inside the jar and water outside, but the jar is still there. The 'I' is the jar.
But love is much like a dam; if you allow a tiny crack to form through which only a trickle of water can pass, that trickle will quickly bring down the whole structure and soon no one will be able to control the force of the current.
