The law of attraction is simply the taking in of what you give out or radiates. It was said that that a person and his ideas/thoughts consist of pure energy. If you are full of positive vibes, have a good outlook in life, it is said that you give out good and vibrant energy, thus you tend to attract affirmative energy. Consequently, a negative person is deemed to attract bad energy. Thus, this will have an effect to a person's relationships, wealth and health. It is based on the idea of attraction between two similar energies. However, I'll have to caution you that the Law of Attraction has no scientific basis and has zero empirical evidence.
