Things that spiritual teachers have told me were true or insinuated were true that I believed at some time but now feel fairly confident are false (besides some of the out-there metaphysical stuff):

• Rational thought and critical analysis are a dead end
• Politics is a distraction
• People who have cultivated a certain degree of spiritual freedom will become more physically attractive in alignment with dominant western beauty standards and will be able to support themselves relatively easily under capitalism
• It is good and right for spiritual teachers themselves to not want to get regular jobs but still expect to lead an upper middle class lifestyle 
• What is most real is happening on a different plane of existence or within a different consciousness, so reasons that seem weak in a “worldly” context are actually quite strong and even enlightened in a cosmic context
• A lot of freedom can be found in just doing what you are told
