Irs actually evil to post something like that. The Foundation of Human Understanding has nothing to do with Yoga or Eastern Religion.
They merely teach a Judeo-Christian form of Meditation that was used by the early Christians and has been lost to modern Christianity.
BS. I did meditation before I came to Christ. The meme that Masters et al are just reviving old meditative practices of early Christians is false. Such meditation is a conduit to great and pernicious evil that can ruin your life for years. Let the reader decide.
