yh Dhan Guru Gobind Singh Ji Maharaaj meditated in his previous life at sri hemkunt sahib.
"The Guru Ji tells us about his previous incarnation, that in the Himalayan range, where there is Sapt Sring Mountain, on that hill he meditated the Name of God. In his meditation when he became one with God, then the Almighty ordained him to take birth in India in order to crush the cruel rulers."
