'Is it necessary for God's name to be written on the heart in order to qualify as being a Zakir-e-Qalbi?' Sayyidi Younus AlGohar answers a viewer's question in this video.  Summary:   - There are three grades of Zikar-e-Qalb (Heart Activation)   1. Sahib-e-Zikar. The minimum requirement for recognition in the eyes of God is for the invocation of God's name be synchronised within the heartbeats. This has to be involuntary. There is a daily limit set by God for how much your heart can invoke his name. Once it reaches the daily quota, it falls silent.    'My eyes sleep but my heart does not sleep.' - Prophetic Tradition  'They remember God while they sit, stand and toss and turn in their beds.' - Koran 3:191   2. Sahib-e-Tassawur. The second grade is when a disciple is granted by his Spiritual Guide to visualise God's name upon his heart. This produces more divine energy than simply engaging in Zikar.   3. Sahib-e-Ism. The topmost grade of Zikar-e-Qalb is when God grants a person his name. There is a lot of protocol involved. This grade is not granted to everybody.   'There are some people upon whose hearts faith has been written. And we have helped their souls with our right hand.' - Koran 58:22
