Meaning
Secrets, mysteries (plural of sirr).
How Iqbal uses it
Asraar means the secrets, the mysteries of the self and of the Divine. Iqbal titled his great Persian poem Asrar-e-Khudi, the Secrets of the Self, making the unveiling of these mysteries his life's theme.

Khulte hain ghulamon par asrar-e-shahanshahi
When love teaches the discipline of self-awareness, the secrets of sovereignty open up even to slaves.
