The Concept of Khudii or the 'higher Self' is synonymous with Allama Mohammed Iqbal, who was perhaps the greatest philosopher-poet of the modern era, his stature and visionary outlook being perceived to be head and shoulders above the times that he and his contemporaries lived in. In fact, the greatest tribute to his stature among poets is that even to this day, poets , academicians, researchers and scholars of urdu, farsi & Arabic poetry and philosophy the world over simply cannot but approach his works except with the deepest sense of awe and admiration at the depth of his thoughts. Allama Iqbal has always been very close to my heart because of his philosophical explanation of Khudii and Sufism, but no man on this earth is greater than our beloved Prophet Muhammed - SAWS).
I think in his life time, the MOULVI, granted him the laqab(title) of Kafar? Perhaps someone will also

stones of hate on people, when they are dead, we worship them".
