Chi Nei Tsang by Mantak Chia

The techniques of Chi Nei Tsang evolved in Asia during an era when few physicians were available and people had to know how to heal themselves. Many people today have symptoms that modern medicine is not able to cure because a physical source for the problem is not easily found. The energies of negative emotions, stress, and tension--all common in modern life--and the weight of past illness accumulate in the abdominal center, causing energy blockages and congestion.
