When you listen to someone explain how the Law of Attraction works they will say like attracts like. That means your vibration attracts circumstances and experiences with a vibration that matches your vibration.
There is an even better way that really explains how the Law of Attraction works: Love Attracts Love
It is an undeniable truth: love is the best vibration you can hold. Love is the truest expression of positive energy that exists anywhere in the universe. There is no other way to better match yourself to the vibration of what you desire. Love is the truest expression of Spirit.
Anywhere you find the Law of Attraction working in an intentional, purposeful way, in a way that is attracting what is desired, you will find love. The law of attraction and love go hand in hand in the creation, attraction process.
“Thought is a mode of motion and is carried by the law of vibration the same as light or electricity. It is given vitality by the emotions through the law of love; it takes form and expression by the law of growth; it is a product of the spiritual “I”, hence it is Divine, spiritual, and creative nature. From this it is evident that in order to express power, abundance, or any other constructive purpose, the emotions must be called upon to give feeling to the thought so that it will take form.”
Master Key System
Love is the feeling part of the creation process. You will attract what you think about and feel about. Since there is no better feeling – no greater expression of positive energy or vibration than love, love has everything to do with it.
