Often we hear, "Is there a right time to die?" Of course there is: when one has been invited back home. When the Universal is waiting. The Light will invite you. The Doorway will open. You will know this with either your senses or your intuition or both. You will look outward ata the world and experience a sense of peace that only the opened Doorway and the Light can provide.
What remain constant in every account of angels, from ancient days to the present, is that they are both messengers and companions to humans, sent from a realm beyond usual seeing. Angels appear, and in one way or another, help us, advise us, inspire us, or amaze us.
