I went to Rewalsar as per what the Tibetan Lamas and Monks had told me in Dharamshala India. Rewalsar is about 5 hours by bus away from Dharamshala by the way. (I just checked and it is still about 4 to 5 hours if you can get a direct bus there and the route our bus took was through Mandi. When I arrived there I and my family stayed at the Nyingma Monastery and all night long the monks at this monastery did a Dorje Drolo Puja in the courtyard below my room that they gave me which was like a Penthouse room looking over the courtyard where the chanting of the Dorje Drolo ceremony went on all night. I felt like I was 1000 or even 1500 years ago about the time that Padmasambhava had come to Lake Rewalsar with Mandarava who was a princess and consort to Padmasambhava at the time who was traveling I believe at this point from Nalanda Buddhist University in Bihar State of India and taking the Dharma (Buddhism) to Tibet. And on the way he met Mandarava who became his Tantric Student.
The story monks told me went something like this. The King, Mandarava's father was upset about his daughter being with Padmasambhava so they tried to burn Padmasambhava at the stake. So, he created a Lake there instead of being burned up and flew up to where I saw his footprints melted into the rocks there where my own Vasques Cascade Mountain Climbing boots fit perfectly into the footprints in the rock there. Then I was asked by Lama Wangdor to come to his monastery there near Padmasambhava's footprints melted into the rock there. I also visited Padmasambhava's meditation caves there as well. Down nearer to the City a Female Monk (when I was there were called ANIS (plural) Ani (singular).
So, the Nun stayed in the Mandarava Cave under the large boulder guarding Mandarava's melted Handprints into the rock trying to prevent the her father the King's soldiers from taking her away from Rewalsar, India and Padmasambhava.
The Tibetan name for Rewalsar Is Tsopema. (Pema) being "lotus" in honor of the Lotus Born Padmasambhava.
