Combining yoga (asanas); qigong meditation and raw vegan diet with Buddhism
There are a few things which come to mind that Buddhism may say about your current spiritual path;
Surely, the practices you have described will bring you some beneficial results. But without proper insight, guided by the Noble Eightfold path, they will not lead you to liberation from old age, suffering, and death. And this is evident by the way in which you describe the body. The body is in fact a prison, not a temple. This body is not ours, and by its very nature seeks out death. Pursuing health is a useless endeaver, as the Buddha said :

&quot;'I am subject to aging, have not gone beyond aging.' This is the first fact that one should reflect on often, whether one is a woman or a man, lay or ordained.
&quot;'I am subject to illness, have not gone beyond illness.' ...
&quot;'I am subject to death, have not gone beyond death.' ...
Upajjhatthana Sutta AN:5.57

And in fact, the mind has far more affect over the body than the body does over the mind, insofar as the mind is developed. An undeveloped mind can and will suffer in even the most healthy of bodies, but a well developed mind needs not suffer in even an ill and dying body. In this way, the two do not mutually affect each other, and therefore pursuing healthy things for the sake of health is of no benefit. Such clinging to your health and well being will only lead to suffering, as sooner or later it will come to an end.
As for asanas, or qigong meditation, I do not know. But unless their teachings ascribe the application of the Noble Eightfold path, they are not in line with the teaching of the Buddha, and will not lead one to final liberation.
I hope this helps clarify some things with your current practice in regards to the teachings of the Buddha.
