Bhai Sahib Randhir Singh Jee mentioned in one of his books that doing Surti da Paath of Sri Sukhmani Sahib along with Naam Abyiaas during Amrit Vela increases ones Kamaiyee by many folds.
Problem is one must have Sri Sukhmani Sahib Kanth and has Abhiyaas of doing Surti da Paath. Until then Sri Sukmani Sahib can be recited by Rasna and Abyiaas can be done in Surti to reap more benefit.
Many Puratan Singhs had this ability to do many banian by Surti while doing Naam Abhiyaas or vice versa.
Daas dire to have Sri Sukhmani Sahib the Kanth, may Guru Sahib and His Sant Jan eh assees Bakhshan.
