Painful removal of anarthas

Sometimes we are so stubborn that we cannot see our own anarthas even when repeatedly pointed out by Krsna through His devotees.... this is when the purification process becomes painful - like having your wisdom tooth pulled out by a dentist and it is yanked this way and that way... so painful .... as the tooth refuse...s to come out.... just as we refuse to see our anarthas and thus hamper their removal.
