The state of leaving everything up to God and doing continuous Naam Simran in the Hirda.  A person who goes into the spiritual stage of Dhyaan gets uplifted so high spiritually, that he reaches the Sach Khand stage.  Dhyaan means going into Samadhi and Sunn Samadhi in the early stages of Bandgi followed by the highest stage of Sehaj Samadhi – which is a 24 hours non-stop continuous Samadhi.
