Follow Gurudeva's teachings in a serious way; take up a daily vigil, sandhyavandana, worshiping at the change of days. It takes time to change and master our character, soften the ego, purify the subconscious. Welcome correction from the living guru. Be on the spiritual path, the path of change. The challege of daily sadhana lifts up energy and the instinctive and intellectual mind don't strengthen unknowlingly.
