Feeling of Superiority and what to do about it?
This is perhaps due to seeing your journey on the path as "self improvement".  Chögyam Trungpa wrote a book addressing this exact issue: Cutting Through Spiritual Materialism that I have found to be very helpful in providing insight to this trap.

Ultimately, the spiritual path involves awakening the mind and eliminating ego.  "Bolstering" the ego may seem to help but often results in allowing the ego to use spirituality to reinforce its own power over your mind.


  If we become successful at maintaining our self-consciousness through spiritual techniques, then genuine spiritual development is highly unlikely.  Our mental habits become so strong as to be hard to penetrate.  We may even go so far as to achieve the totally demonic state of complete "Egohood".


Also from this book:


  Retreat to nature, isolation, simple, quiet, high people-- all can be ways of shielding oneself from irritation, all can be expressions of the Lord of Form.
