Speech of opposition : It is Farz to have ‘Huzuri Q’aalb (pure and fresh mind). But it is Mustahab to have a Peer Saheb.
What is said in Islam : Both having Huzuri Qaalb and Peer Saheb is Farz. To have a fresh mind it is necessary to learn ‘Qaalbi Zikir and Tasaouf, it is necessary to surrender oneself to a true Peer Saheb. Without surrendering to a Peer Saheb it is not possible to earn “Qaalbi Zikir and ‘Elme Tasaouf. So Surrendering to a Peer Saheb is Farz.
