How to get rid of thoughts of grandiosness?

By practising the eight fold path and meditation I have been able to get over lot of suffering as a result of my past created by my mind. I am able to get over self pity, hatered, anger by following the advise of friends in this forum... But now that I am over the past my mind has started playing new game...it starts painting pictures of grandiosness...like it presents me with illusions like i will be as great as the Buddha...I will be the Buddha and have followers...i will have super powers...i can fly etc etc... Its getting difficult to control these thoughts in meditation...its a kind of hindrance I didnt read in any book... I want to attain silent present moment awareness...is there any sutta which can help me with overcoming this maya of my mind? Is there any help?
