Studying the Universe
Way back in a simpler time
The great mother showed you rhyme
Way down in the feeling tree
The mind calms and urges lead
Use your heart to find the key
The key note starts the tree
A hidden energy finds your need
And appeals to you through hide and seek
There exists a system of patterns, like the notes on a musical scale not being immediately apparent, only hearing noise at first, then "discovering" or isolating out the musical scale by subdividing vibrations.
This is like a new dimension. A dimension is something which has a range of values, so we have time, space, color, size, etc., all as dimensions. But this dimension is like the next step of consciousness. Like before we were blind, and now we can see a super bright light, and get warmed and tingly by its presence. It is some sort of signaling network, using associations and signals.
This new dimension is basically experiencing reality at a much deeper level than one can possibly imagine given basic current levels of consciousness and blinding. One can still "block out" the awareness and be a human after moving to the next dimension, or you can dig into the awareness and move like a kaleidoscope through different planes of potential and experience.
Somehow we as lifeforms on Earth are bound, physically, to this body and so our experience is somehow physically limited. But according to the ancient sages, we continue on after our physical death through all kinds of experiences into a deep consciousness or "mind".
