Speech of opposition : It is Farz to have ‘Huzuri Q’aalb (pure and fresh mind). But it is Mustahab (Optional) to have a Peer Saheb.
What is said in Islam : Purification of mind and having a Peer Saheb both are Faraz. The only one media for purification of mind is ‘Qaalbi Zikir. And the only one media to learn ‘Qaalbi Zikir is to sacrifice oneself to a Peer Saheb. It is not possible to have a fresh spirit or learn Tasaouf and ‘Qaalbi Zikir without sacrificing to a Peer Saheb.
