Sampa Nyur Drupma
The prayer starts with the words "emaho tso ü gesar pémé dongpo la..."
It says in the colophon:
This prayer should be kept in the hearts of all those with faith, who wish to benefit the land of Tibet, pacify illness, prevent famine and border invasions, and contribute to the welfare of the teachings and beings.
The first stanza is taken from the verses of praise in 'The Infinite Cloud Banks of Profound Meaning' (Zabdön Gyatsö’i Trinpung), the ‘background teachings’ to the omniscient Longchenpa’s Khandro Yangtik, and the later verses are the blessed vajra words of the second omniscient one, Rigdzin Jikmé Lingpa.
