You dolt! If this were true every sailor, high construction worker, rock climber, and mountaineer would die because the wind would upset their tender Chi balance! If meditating in the wind causes a person imbalance of any kind it is due to a preexisting infirmity or over-exposure!
There is nothing different or special about meditating in the wind than any other activity.
You are completely ignorant!
Start living in the 21st century!
I am not talking about imbalance.
I am talking about when Qi and physical body open up in a certain condition, the Wind can penetrate in with no shield, if it unfortunately get into the bone or the internal organs then That cause big problem.
This could even happen if one doesnt settle the body down one's body to normal state before walk into windy area after the meditation.
Stop using your mind to speculate on what you dont know.
