Forget your dhikr. Forget yourself.

Bismillah.

Those who remember their remembrance of God (dhikr)

are more heedless than those who forget their remembrance.

- Abu Bakar Muhammad bin Musa Al-Wasiti

O son, the point is, do your dhikr but do not depend on it. Forget it. Better still, forget yourself and wake up to your Lord. In the words of Abul Hassan al-Aswari:

"Sufism is my forgetting myself and my waking to my Lord."
