Landmark Forum (or Landmark Education) a personal development program. Originally, it was Werner Erhard’s EST. A group purchased the intellectual property rights of EST and added more training to attract a broader market.
Much criticism has been directed at Landmark. It is categorized as an LGAT (Large-Group Awareness Training) and is the target of accusations of brainwashing. My personal experience with Landmark is that they use psychological manipulation techniques to challenge one’s view of reality. The main idea in my experience is that nothing has value beyond the value we assign to it…as a result, they teach that there is no right or wrong, no good or evil, unless we think there is.
Obviously, Landmark is not compatible with Christianity.
