Love is a state of Being. Your love is not outside; it is deep within you. You can never lose it, and it cannot leave you. It is not dependent on some other body, some external form.
In the stillness of your presence, you can feel your own formless and timeless reality as the unmanifested life that animates your physical form.
You can then feel the same life deep within every other human and every other creature.
You look beyond the veil of form and separation. This is the realization of oneness. This is love.
What is God? The eternal One Life underneath all the forms of life.
What is love? To feel the presence of that One Life deep within yourself and within all creatures. To be it.
Therefore, all love is the love of God.
