As we advance in the art of  meditation first we penetrate into the realm of the subconscious and then into the unconscious, where we find ourselves interconnected with the totality of  the manifested universe and  all the beings that arise in it. Because the unconscious is operating not through linear thought and rather through symbols and archetypes we may lack words to describe what that in reality is. But as the  subconscious and unconscious are entered with conscious awareness it is purified and gradually enlightened and we move down the  hologram, learning to perceive ourselves as a reflection,  a smaller scale hologram or a microcosmos, within the  grater hologram or macrocosmos of the Self. 

This happens when our identification with our limited self, the path of separation of the soul, is dropped and we move downwards to the Source. If we reach a level where we can see that our true identity is Divinity or the Self, it is because our heart has grown to that maturity of experience.  It is also when we are able to track the origin of any diseas in the subconscious as remove clashes from belief systems and emotional experiences that the heart registered as contractions in our identity.

It is our physical brain and our mind that sometime still needs to interpret reality as something that is outside of us and understand if there is anything "out there" beyond the great holographic universe. But we can only answer that  if we also expand through the Heart and watch how the Source that is projecting itself through us is also projecting itself in other beings that are either manifested physically or exist in non physical realms. Sometimes these are called inner plains or dimensions of reality and some of us reach these plains through dreams or meditation and gain some insight of their nature.The physical plain is only one of those realms but all others plains are in truth also embedded in the depth of the Now. The relation between the expansion of the Heart and the understanding of the mind is what permits us to be open to such perceptions, but we have to let go of belief systems to communicate with those plains or with any particular entities. 

However, once we let our heart dwelve into Oneness the ilusion of separation and other entities is clarified and we understand that it belongs to the duality of the mind, which is not yet liberated from former beliefs. After this understanding takes place there can be only a conscious decision whether to continue evolution within separation, investigate  and explore this Self created universe or melt down into Beingness. This is what determines for us if we move "up" the Hologram towards adventure within seperation with a particular agenda or move "down" towards absorption and disolusion in the Source.
