The mind may not be interested to admit and it may be a challenge to clearly see, that the mind causes all of its own discontent feelings.
Sadness, anger, frustration, irritation, annoyance, guilt, shame, fears, boredom, loneliness, shyness, jealousy, resentment, stress, anxiety, etc. are not caused by others but instead, by one's own mind.
Seeing this clearly, is the first step towards liberating the mind from 100% of all its discontent feelings to attain Enlightenment.
