The process of manifestation is actually like going to a supermarket where everything is there, sitting on shelves for you to have it, only you are not paying with the money but directly with the energy of unconditional love which you have to use in a certain way.
The key to the successful manifestation is about your state of being and the level of your awareness.
It is about your awareness of what you really need, while not being attached to that need at the same time.
It is about asking what you need from the heart space, while not being selfish or greedy at the same time.
It is about being grateful as though what you need already happened, but being alright even if it does not ever happen.
It is about living the present moment, while not thinking or focusing too much on what you already asked for in a manifestation process.
It is not you who is creating any of what you wish, you are just inviting in your life what you really need and the Universe is providing you with what is already there.
