Practice to spot angelic presences
It takes practice to spot angelic presences. But practice alone is not enough, unless one can practice being taken by surprise.
Choice is your greatest power ... even a greater power than love, because you must first choose to be a loving person. Take the example of someone apologizing to you for having spoken thoughtlessly or hurtfully. In that one instant the power of transformation rests entirely with you. You can gtranscend the density of your anger and choose to forgive, transmuting that instant into an exchange that restores energy to both of you. Or you can repress your divine nature and cause the potential opportunity for healing to become a contaminated energy transaction.
