Sir Iqbal was undoubtedly one of the greatest poets, philosophers and seers of humanity of all times. He took a prominent part in the politics of the country and in the intellectual and cultural reconstruction of the Islamic world. His contribution to the literature and thought of the world will live for ever. In 1915, he published his first collection of poetry, the ASRÁR-I KHUDÍ (Secrets of the Self) in Persian. The poems emphasize the spirit and self from a religious, spiritual perspective. Iqbal proves by various means that the whole universe obeys the will of the "Self." 
His message is not for the Mohammedans of India alone, but for Muslims and non-Muslims everywhere.
