Master Zhao Ming Wang (Beijing) tends to favour 'face-to-face' instruction due to the teacher being able to 'adjust' the energy imbalances. In other words, treating any outstanding illnesses and ailments with Daoist medicine (pressure points, herbs and exercise). However, when this is not available, then 'neidan' becomes the focal-point - or 'self-study' through self-cultivation. In this sense, we all form a supportive 'net' around the world helping one another on the path. In China today, Western medicine exists side by side with TCM, and people can choose and switch between these systems. Obviously, acute, chronic or severe medical issues should be treated with the correct medicines if available as no amount of will-power will cure a physical ailment. On the other hand, preventative medicine probably does work but we are never aware of the illnesses we do not catch! Sometimes, I have had the honour of working with those who are 'dying' from an incurable disease and the issue is then one of psychological and emotional transcendence of the body (loosely termed 'spiritual').This must happen whilst the individual is still within their body and before the life-processes come to an end.
With Best Wishes
