The love which is within you is inexhaustible and limitless. You have the capacity within you to love everyone anywhere. It does not matter if there existence is known to you or not. It matters not if they are on this planet or on the far side of a dozen galaxies away.
Love is a fire which perpetually burns within you. Even if you have actively done your best to wall it up and dim it's light shine. For you to continually destroy the love within you means you must destroy yourself. Then from your own physical destruction will you only free the love which was within. Now, all of those who can see, will see the love which always was.
