Someone mentioned that the Law of Attraction is something I should practice

I know I have manifested things in the past, specific things. I know I should know more about it.

I can’t say I practice manifestation regularly, but I know it occurs. Usually it is in hindsight that I realize I had daydreamed about something and it came to reality.

I do read a lot, and have known about The Secret since the book first came out. I am fascinated by the interaction between conscious and subconscious and unconscious. (I believe there is one more level of consciousness above conscious… perhaps super-conscious? Perhaps a better term is group-conscious.) This may simply be resulting from my fascination with the number four. My intrigue with the number four is why I am writing a book about the four aspects which make up an individual: Instinct, Intellect, Intuition, and Intention.

How must I align myself with Manifestation (Law of Attraction)?
