What is Lhodrak Kharchu?

Lhodrak Kharchu is a province of Tibet and the location of the cave of the great saint and father of Tibetan Buddhism, Padmasambhava. This cave is one of the locations in which Sogyal received an opening of the mind at the hands of Master Khyentse. After a traditional invocation of a lineage of masters, Khyentse suddenly asks Sogyal "What is mind?" Sogyal finds himself without words or thoughts, and glimpses the nature of mind, or enlightenment.
