Re: Dhikr
LP, no doubt the general Dhikr that you do would also have benefits (even if you cant see them). If you do not see them, then why worry? You are still remembering your creator!
The dhikr that is prescribed by Shaykhs follow centuries of tradition from Tariqa masters. The dhikr passed down by a Shaykh is full of Sir (secret) which the master knows and conveys to his Mureeds.
Attend a Dhikr gathering LP for Dhikr in a gathering is far better than Dhikr alone!
