Imagination is the only tool available to unlock the infinite creativity that lies within us all. Since thoughts become things, we should strive to have unhindered access to this infinite pool of possibilities, and it seems the possibilities are filtered the by human ego. The ego is usually the only thing standing between you and anything you can possibly imagine because the ego is what prevents belief. I guess limitations caused by the ego vary from person to person but it seems that in the absense of ego, the soul can shine while creativity flows freely.
The trouble is convincing your ego that it actually exists, and kindly asking it to step aside so the soul can do its thing. In current society, fear rules the psyche. We are stuck in a prison where our minds are focused on survival, while the light of the soul fades from until it is simply a notion. This is where entheogens show their colours. It is the altered conscousness that entheogens provide which allow for ego suppression and keen awareness of the infinite pool of knowledge that we can tap into. The soul and the ego can introduce themselves to each other, collaborate or even argue. It all plays out like a symphony before your third eye allowing you to 'see' the beauty of reality from a completely different and elightening angle.
Entheogens certainly show the mystery of the world and as Einstein said, "the most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed."
