Asrar-i-Khudi (Secrets of the Self) was the first poetry book of Iqbal. Considered by many to be Iqbal's best book of poetry, it is concerned with the philosophy of religion. Iqbal wrote this in Persian because he felt the language was well-suited for the expression of these ideas. This book deals mainly with the individual, while his second book Rumuz-i-Bekhudi discusses the interaction between individual and society.
