Aloha,
The lower dantien question comes up frequently, as the "below" which is refered to so much in related forms/work , can be interpreted as toward the feet or toward the center of the body from the navel. Master Lin usually tells a story about putting the question out in his meditation and three of his Masters showed up and pressed into and behindhis navel. From then on he's used "behind" so it's clearer.
It's interesting the number of friends also in the martial arts are almost excited when they hear him saying "behind". It's almost a "coming out of hiding" for them as they start sharing how that's where it's always naturally focused in for them too, but the people and style they've studied under kept saying below (toward the feet).
Much Love, Shawn
