Let not your heart be troubled: ye believe in God, believe also in me. In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
When Jesus speaks to his apostles, he speaks in his role as Christ, the consciousness that is the same as the Father, as God. This consciousness is a vibration of non-resistance, of knowing one's infinite power and ability to manifest all things wanted. We have another word for it as well.
It is IMAGINATION!
He is the imagination that opens the way for the physical experience of the thing imagined. When he says that he goes to prepare a place, what he is saying is that imagination is what establishes vibration, and vibration attracts the end result.
If you look closely, you'll see that, in one way or another, almost all Jesus does in the Bible is talk about the law of attraction.
He knew that imagination was merely a translation of something that already existed, but had not been brought to physical manifestation.
If you want to find out what the best version of your world could look like, use your imagination. If you believe that what you see in your mind's eye is real, you will soon see it in front of your face when you open your eyes.
Imagination is the seeing of the not-yet-manifested. It is the translation of a truth that can only be sensed, until someone has been willing to "go and prepare a place".
Imagination liberates, because it shows you the actual limits of the mind and its power to create.
There are none.
