That moment between sleeping and waking up is a portal. That is the same moment used in deep meditation to travel to the realms of the astral, and beyond. So, to access the beyond one will need to go through a state of deep relaxtion where one can then shift consciousness to another dimension, and then instead of shifting to another dream/dimension one begins to pull all attention to the inbetween space. That one moment in which you go to sleep in one realm and wake up in the other. That is pricisely when one can pull all attention to the inbetween by deleting everythng they know. Picture your memories like pictures in the smartphone, and then start to delete them. Once they are all gone, you delete the phone, the hand holding the phone, the world the phone exist in and then all the light everywhere. Now you are in the unmanifested source material that permiates from the beyond, delete all concepts tied to where you are. When you are completely deleted, you will know because you would then be in the beyond. Hi Beyonder!

The beyond is a field of raw source materials that one can pull from to create. To go beyond, simply desire to create something new. The building blocks will then be manifested towards its creation.
