If you have a sense that anyone is draining your energy, mentally cut the etheric psychic cord between you and the other person. Be willing to forgive that other person for seemingly draining you, and release the other person fully to the light, now. Completely let go of focusing on personalities of other people and ourselves, and focus, instead, on the true oneness of your spirit.
Earth has scarcely an acre that does not remind us of actions that have long preceded our own, and its clustering tombstones loom up like reefs of the eternal shore, to show us where so many human barks have struck and gone down.
