Bones …

There are many things people don't realize about bones and spiritual cultivation. For instance,

* the bones transform after many years of practice
* you can tell someone's fortune by feeling their bones … including the fate of their status in life
* by telling if someone's bones are heavy or light, you can even tell how difficult it is for them to cultivate

The bones, after the interstitial spaces between body parts, are the most difficult parts of the body to transform via spiritual cultivation efforts. In fact, some people have it tougher than others in cultivation because of the density of their bones.

What they inherit as bones is the expression of their genes, of course, and behind that a function of their merit. People say this is due to genes and that is due to genes, but they never ask WHY did you inherit THIS speciifc set of genes in the first place. That's karma and merit.

Also, they never realize that genes aren't your density - it's what you wash over your genes and expose them to that determines what and how they express. In other words, behavior determines fortune.

To explain the relationship between your bones and cultivation  would take a lot of time and frankly, most people wouldn't understand the topic at all, as smart as they might be, unless they already had achieved a degree of gongfu where their chi channels had opened up from meditation efforts. No gongfu, no understanding.

Best way to do this? Breathing methods combined  with the skeleton visualization method, or even Esoteric chakra visualizations as espoused by Tibetan Buddhism, Hopi Indians, and Persian cultivators as well as western alchemists. And mantra for the merit or help to succeed in the process too.
