The Third Eye is the Doorway to the Heavens and Simran is the Key

"Recognize the Path to your Beloved, O travelers and take the route of the anguished lover in separation. Keep the Master’s grace in your thoughts, and reflect upon his pure teachings. Develop love and devotion with endearment, and keep the thought of the Creator always before you. Try to merge yourself into God like water and water. Fix your mind within by following the Path of the Sound Current. A yearning will arise; make then an intense and anguished call. Repeat the Name of your Beloved, day and night, again and again and again. With care in thought, word and deed, you will cross to the other shore." (Sant Dadu Dayal)
