The mind must still be ‘calmed’ before these methods work, regardless of lineage. However, Zhao Bichen considered his main masters to be two Ch’an Buddhist monks (who together passed on the Wu Liu Daoist lineage to him). Their input added the Ch’an method of ‘hua tou’ to the Daoist practice.
in other words, a lineage descendent can be trusted not to be motivated by greed (or any other selfish distraction), and to be motivated entirely by an altruistic compassion. However, this altruistic compassion must not be confused with sentimentalism, or attachment to person or process. Obviously, you may wrote to me as often or as little a you wish.
