This is a big question for many and here is the answer.
Be sure to use a vaporizer if taking in any kind of smoke. http://www.amazon.com/M107-Model-Arizer-Portable-Vaporizer/dp/B005C... If your house is humid be sure to use a dehumidifier pulling the air down to 60% humidity at least. Work with the Lung Rejuvenator located in the Internal Cleansing Kit. http://www.internalenergy.org/forum/topics/lungs-kidney-and-bladder...Most importantly learn to build Prana. It is this energy that accelerates Spontaneous Regeneration and it is in this area when following these instructions you will see significant increase in lung strength and the real activation of Spontaneous Regeneration. Wholeness, we are with you.
