Asrar-i-Khudi (Persian: اسرار خودی, The Secrets of the Self; published in Persian, 1915) was the first philosophical poetry book of Allama Iqbal, the great poet-philosopher of British India. This book deals mainly with the "Self" in relation to the universe, how it is the inner power and soul of each individual human. It instructs on how to improve the Self through Love and willpower, which can then help one control the forces within the universe.
