You can't suppress your inferiority complex. You can't suppress your delusions of grandeur. Let these two suppress each other, then you will attain the virtue of dispassion. If you suppress yourself, one of your vices will grow and devour you.
What can I tell you about the inferiority complex? I haven't seen people who don't have it. I, for one, have a monstrous inferiority complex that barely makes up for an equally enormous megalomania. Ideally, these two are compensated and become dispassionate.
Blessed are the poor in spirit, because they have managed to get rid of the inferiority complex and megalomania. The endless split personality and the war were over. Within was incurred pleasant integrity and purposefulness.
Interestingly, the small pride comes from their megalomania. And the pride of the big ones stems from their inferiority complex. The little ones suffer from megalomania, and the big ones suffer from inferiority complex.
