I am so fortunate to have found this post with such beautiful and holy images. The cave where Pabongka Rinpoche meditated in, in Tibet.
It has been told that after receiving a teaching from Pabongka Rinpoche's Guru, he would go into this cave to meditate and reflect on the teachings, of which later Pabongka gave a 24 day teaching, recorded and written by Trijang Rinpoche of which we now study as the Lamrim.
Would be wonderful to be able to visit this holy place. Wonder if it is open to public?
