Love in the way that you love, unfettered, because love is there to serve no one and nothing but itself.
As a person in this human experience, we can always choose to alter the way it manifests its demonstration, but not love itself. If you feel it inside, don't restrain it to match that of those around you. Let it be and let it flow if even in thought* alone. For if you can diminish and take from it, I beg to question if it was really love.
Love is complete.
Love can sing in a round, even a capella.
*In cases of unrequited love, it is important to let the thought pass through, and not to dwell. Let love come in and let the thought flow through...through you, in then out, not to linger for too long. Love does not need a subject to warm you.
