A long time ago Yeshe Tsogyal asked Guru Padmasambhava what could be done to help beings in the dark ages she foresaw. What could be done to alleviate their miseries in the time of the Kalpa of Great Conflict, the Kalpa of Weapons, and the Kalpa of Famine?
Padmasambhava answered:
“In order to help eliminate intense suffering in that dark time, make supplications to one who is now one of my twenty-five foremost disciples, and who in the future will bear the name Karmapa. Sincere supplications and devotion to that being will bring about harmony.”
