Have you yet found the immutable core? It is found in the stomach, the seed grows from here.
Atoms have one, planets, humans, trees… everything micro-cosmically and macro-cosmically repeats itself endlessly in every phenomenon, across all dimensions.
To root oneself in the core is to know oneself as the immortal essence.
The core is in the stomach, it grows like a seed from there.
The eyes look at the end of the nose, the breath is deep into the groin, stomach and chest but is inaudible.
On the in breath the energy/breath moves up the spine to the crown, the clouds gather, the tongue is placed on the roof of the mouth to connect the channel and on the out breath the rain/ energy falls down the central channel to nourish the seed and the process is recycled with the breath.
