You are present by entering the body. There is no other way to be present.
The human body is (among other things) an instrument or technology of reception. Reception is local. The body receives signal from the position of here.
If there is experience that is inaccessible to me, it is due to some lack in my instrument (toxicity or lack of knowledge/training). It means my body is challenged by the reception of signal and/or is challenged with the handling (mediation) of the signal once it is received.
Our self receives information from the universe through our body and our five senses. There is no other path of getting information. All universe/multi-metaverse/reality information passes through the filter of the body. (Information means signal.)
The eyes receive the signal of light (photons).
The ears receive the signal of frequency, or vibration, of matter (atoms and molecules).
The nose and tongue receive the signal (and indeed, contact) of molecules.
The skin receives the signal of frequency (vibration), the signal of atomic speed (temperature), proximity (pressure and touch), and perhaps more.
There are other body parts (organs, and energetic structures such as chakras) that receive (other) signal (other energies). As well, individual cells of our body have experience by the reception of (or contact with) atoms and molecules.
Through your body and its five (plus?) senses, you sense energy in its various forms and states.
Once signal enters, is received by, the body, then the body and the self begin the task of mediation--the mediating of experience. I will not discuss mediation fully at this time, but in essence it is how we interpret and give meaning to the signal(s) we have received. It is our perception and our paradigm. We have the opportunity to choose and craft our mediation paradigm. As well, often it is a relief to have a minimum of paradigm and to experience the signal around us in as raw a state as possible--to simply be present.
Our experience in the body is not an inferior, profane, or carnal experience. Our experience and presence in the body (and therefore this universe) is a sacred, temple experience. It is possible to profane the temple, yes (toxicity). It is possible to have the five senses of our instrument clouded or our mediation capacity toxic. But we can also purify our senses to their most healthy, natural state.
It is not an illusion that you are HERE. HERE is reality. Signal is also not an illusion. Signals in their raw state are reality.
Honor the senses of your body and explore your world through them.
