Hakeemul Ummat Hazrat Mawlana Ashraf Ali Thanavi ra said:
“The suhba (company) of Sheikh is most beneficial only if the mureed is consistent in zikir (remembrance) and shugul (special concetration excericse for recollection) prescribed by the Sheikh.
There are individuals who are always around the Sheikh but do not do the wird prescribed. They do not benefit at all and always remain deficient.
And some others spend most of their time with the Sheikh and spare a short interval to do some zikir & shugul hapzardly. This is also not beneficial.
The major portion of the time should be for the prescribed zikir & shugul (i.e wird). Only then the suhba (company) of Sheikh is beneficial.
