The difference in attitude and teaching between these two schools of thought is tremendous. One says that nothing else is needed than the finding of the real Self, for that will automatically wash out all faults and shortcomings. The other says that only by eliminating those faults and shortcomings can the real Self be found. Zen Buddhism and Ramana Maharshi belong to the first school, and Martinus to the second one.
