vibration manifests as a result of proper application of fundamentals - you need ongoing deep stillness otherwise such events are fleeting and spurious. similarly, in deep meditation, if you start focusing on the light show and forget about that which makes these phenomena manifest in the first place....buh bye manifestation-events.
And when you say fundamentals, it literally is fundamental - fundamental harmonics/modes.
There is a heat in my spine I notice comes and goes as with the opening/closing of the central channel/sushumna nadi. The aim is to keep this heat constantly present and flaming very gently, as a candle flame that lights up through the spine and the vapor reaches the third eye & crown thereby illumining everything with divine light/awareness.
There is a corresponding posture correction effect. Keeping this spinal heat up is the key to maintaining meditative stillness and the breath is infused into every little motion. The lower dan tien automatically opens up and through correct breathing flow one naturally keeps it open.
We have many habits of modern living that over time shall inherently restrict the airways and close the LDT so it is of essence to cultivate habits that open it more than close it the majority of the time. I have made a conscious decision to get off the PC and start walking a lot and switch to a kneeling desk and these things vastly help.
Now... the vibration of deep meditation!
It's the breath cycle and the brainwave cycle!
So you have this breath travel up and down the spine, in effect from the heels right to the crown - whole body breathing! First with practice it appears more so just up and down the spine itself as a warm rush felt in the back then flowing with it will unlock the heel breath naturally effortlessly.
The brainwave cycle is important. There is a physical stillness to the way of movement. When movement become smooth, the breath cycle is smooth. When the breath cycle is smooth, the brainwave cycle is smooth. When the brainwave cycle is smooth, the Tao is realised in that moment.
There are fundamental modes to this spine breath energy (your Spirit). The first mode is a perfect slow 1 cycle breath where it is as if no breath is necessary altogether (Samadhi). Then you have harmonics of this breath, modes of the standing wave. If we are rushing around day to day making jerky movements then this Standing Wave of the Breath is thrown off and connection to Tao is distanced.
So you have maximal in<=>maximal out, that's mode 1.
The natural state free of all thought is maximal in<=>maximal out
Then we have interrupted breaths, which occur via thought-trigger - a thought triggers direction flip of the breath flow.
Any thought => (Direction of Breath) * (-1)
The reason this happens is that each thought collapses everything into a Yin or a Yang, a Male or a Female, a duality/polarity. The breath changes direction to resonate this energy that Thought chooses to focus on.
Then we have the dynamics of Yin-Yang that generate the music of the breath itself. Breathing at X cycles per second, interruption/flip points, the still points between breaths (out=>Still Point=>in=>Still Point=>out), heart rate.
The correct natural state of abiding aligns the breath cycle with the heart flow cycle. This will cause the Central Channel to open and resonate like a radio antennae. The standing wave of breath oscillation travelling up and down the spine via nerve conduits/heat flux, the standing wave of a heart in total peace and remembrance of Supreme, the standing wave of the brain's electrical oscillations.
The last one is of keen interest. It is known that monks have heightened gamma wave activity in addition to standard delta<=>gamma range activity. From what I have heard and feel from experience, the high gamma wave resonances are primarily sustainable in the fertile garden of a deep delta wave resonance. Then the harmonics of the waves present a kind of stillness-in movement-in-stillness aspect where typically the high gamma activity might have been directed toward anxiety.
The physical heat-energy-momentum wave of the breath is directly the emotional resonance of the heartbeat is directly the brainwave resonance of Mind.
What we want is that maximal Yin/Yang points of Mind are directly simultaneous with maximal in/out points of inhale/exhale, and at all of these times, there is a perfect equal and opposite resonance so that the sum total is 0. The experience then is pure stillness, peace, serenity, fluidity.
Tremendous amounts of electrical energy can be built up in this process and best of all, this energy is yours to keep, it is You, so keep it, conserve it and share it, but conserve it above all!
