Comparing Neo-Daoism with Karezza by Marnia Robinson and Gary Wilson Sadly, Chia’s own experience led to this same outcome. Two visitors to his center in Thailand (one an insider) independently informed me that he left his wife of many years, in pursuit of a young girl from the local village. This behavior is very consistent with the Coolidge Effect. It’s quite inconsistent with the experience of merging deeply with a lover in the “valley orgasm.” That experience, which has been alluded to in various traditions, is a spiritual experience, which enhances vision so we don't feel compelled to follow biology's dictates in our mating choices. Recently, I’ve had the gift of input from two men who have used Chia’s system for years. One reports that he has no desire for a monogamous relationship, and resents his partners’ desire for one.

 Comparing Neo-Daoism with Karezza by Marnia Robinson and Gary Wilson Incidentally, Chia's book Taoist Secrets of Love: Cultivating Male Sexual Energy does mention karezza, but describes its history, its goal, and the technique itself quite inaccurately on pp. 60-1:
To clarify, Karezza did not originate in Persia. It had nothing to do with harems. It is not about increasing or prolonging physical pleasure (or performance of any kind). It is ideally a spiritual communion of souls, according to both Stockham (who gave it its name) and Lloyd. Therefore karezza certainly does permit "true depth."
