Portals are supported by general consensus. They are the rhythms put forth by our conditioning. They blind our body consciousness by occupying it.
The way to get behind these portals is to cultivate inner silence and what inner silence does is allow you to intend, pure intention.
The quandary is, have you truly achieved inner silence? Are your intentions in correspondence with your body consciousness or with the rhythms of your socially conditioned mind.
