Our body is of the earth and belongs to the earth

The body has various cycles:
Input cycles:
# Hunger cycles = EARTH ELEMENT
# Thirst cycles = WATER ELEMENT
# Sleep cycles = ETHER ELEMENT
# [Sights, Sounds] consumption cycles = FIRE ELEMENT
# In-breath cycling = AIR ELEMENT
Output cycles:
# Poop cycles = EARTH ELEMENT
# Urine, Sexual cycles = WATER ELEMENT
# Exercise/Activity cycles = FIRE ELEMENT
# Out-breath cycling = AIR ELEMENT
# Waking state awareness cycles = ETHER ELEMENT
The elements part may not be exact, but I used my intuitive feel to arrive at them.

The body belongs to the earth, and is made up of the earth.
It is an organic machine, built from the elements of the earth, and on death, this entire body machine will be returned to the earth (which will cycle the elements back into itself).
The body emerges from the earth, gathers earth elements onto itself and grows, maintains and renews itself periodically from various elemental transactions with the earth, and then once its time is over, the earth reabsorbs the body back into itself.
The mothers womb provides the initial body as a template, that then separates from the mother, gathers on the elements (what we call growth), and then stabilizes itself in transaction with the elements of the earth.
“On death, the earth will take back the body, atom by atom” – Sadhguru
I have heard Sadhguru(Jaggi Vasudev) on Youtube speak about this topic many times, but only now I feel like I understand it more deeply.

So from the body’s perspective:
It cares about: food, water, sleep, sex, breathing, preservation.
Each of these activities give pleasure, but only as per the cycles.
The pleasure from the body is limited to the cycles only.
When you are hungry you can only eat until the hunger is satisfied, only till then will you get pleasure.
The same holds true for thirst, sex, and even the breath.
Breathing in is pleasure until you get full, breathing out is pleasure until you get empty.
Since all of the elemental transactions are in a cycle, neither can you preserve, nor can you indulge.
It is like your breath.
You can’t endlessly breathe in, neither can you endlessly breathe out.

In terms of source energy, the highest tangible conception of that for us, is the “Sun”.
But we can use only a fraction of that energy directly, and we need all its other stored forms available on earth to survive/thrive.
Sun -> Plants
Sun -> Plants -> Animals
Water -> stores the heat energy of the sun (else without the sun it would turn into ice).
And then we further cook the plant/animal material in fire, and then we have “energy and elements” in a form that we can easily consume.
The earth itself maintains its temperature from the sun.
The core of the earth is almost like a micro sun.
Human bodies are like the most developed neurons(brain nerve cells) of the earth.

Also with only one half of the earth facing the sun at any given point of time, and with the earth constantly rotating, it is always cycling through duality.
Though the sun(source) is ever present, ever radiant, it is eclipsed from influence and view during the night.
So I would think that is why, in the microcosm of our bodies too, we have the sleep and waking cycles which is a correlate to this macrocosmic duality.

My experience of reality nowadays

I experience reality nowadays as a “changing/shifting ocean of sensation”.
In this ocean, various waves arise, from various apparent centers of consciousness that get formed, and various potentials are then available for various thoughts/feelings/emotions from these centers.
Another way to put it would be, my experience is like the movie “waking life”, i.e. like an endless moving lucid dream.
Another analogy would be, my experience is like a movie that is playing all the time, and I alternately engage with it in various ways, and then disengage in various ways, to come back and engage with…and so on.
I do not have much enduring identity day to day.
And my sadhana/effort is to return whatever remnant identity is there to the ocean.
I feel like I am a witness, that witnesses the whole changing ocean of relationship, where an “apparent I” and an “apparent world” appears and keeps shifting.
It always feels real in the moment, just like a dream feels real, but I also know that everything can change from my own memory of that happening a zillion times.

My experience is like the mantra AUM along with the pause.
Inbreath:
Pause = the recharge of inspiration/energy.
Drawing the formless/unmanifest to form/manifest potential.
Outbreath:
Expression in form/manifest.
Aaaaaa = Waking
Uuuuuu = Dreaming
mmmmmm = Sleep
Inbreath:
Pause = the recharge of energy.
…and so on.

Sympathetic and Parasympathetic Nervous system

tumblr_inline_muo0m7kabj1rmxgp4

There is downward energy flow = para-sympathetic nervous system(psns) = sleep(surrender, rest, relaxation)
And upward energy flow = sympathetic nervous system(sns) = doing (includes all attention, consciousness, thinking, moving)
These are 2 energy flow directions.

The self/ego (conventional) = sns (it is an identification with a certain activity of ‘doing’/verb).
When satisfied or exhausted – psns takes over and sleep happens.
Highest sns/Lowest psns = highest waking point(waking)
Low sns/High psns = dreaming
Highest psns/Lowest sns = deepest sleep point(deep sleep)

sns = pingala = male = doing = solar = order = anti-entropy = motivation = seeking = waking/dreaming = left brain
psns = ida = female = relaxing = moon = chaos = entropy = de-pression = assimilating = sleep = right brain
sushumna = harmonizing = transparent = transcendent pov = neither wake nor sleep = turiya = corpus callosum(brain)
