He goes to all humans in whose heart the red angel has found true love, and he touches them with his ray of light. Then this light penetrates in the hearts of those humans and warms them from inside.
Is like the sun itself would ilumine through their eyes and descend through hands, feet and all the body. Even the poorest of man, the most humble ones, are transformed and start to ressemble the angels, if they embrace some love in their hearts.
But not everybody sees this white angel. Only the rest of the angels and those men who have been ilumined with his light. This light is the same that on Christmas day makes possible to see the child in the manger.
