"The only means that is permissible in attempting to win someone’s friendship and affection, is that of light. The only means acceptable to Heaven and which is also the most powerful is light. So if you want someone to think of you and love you, send him a gift of spiritual light, a bouquet of light; surround him with light. If you do this, his soul, feeling the presence of a beneficial entity, will appreciate you more and more. Do you want your friends to be pleased to see you when you go to visit them? If so, before you go into someone’s house, stop and recollect yourself for a few moments and picture that house and all who live in it bathed in light. If you do this how could they be anything but pleased to see you?" - Omraam Mikhaël Aïvanhov
