Du Tri Su is the heart practice of Bon to clear the karmic conditioning and suffering of the lower realms and the obstacles in our present life. It is a powerful practice to call upon the souls of the deceased, offer them guidance, and help them find peace and wellbeing. The Du Tri Su mantra strengthens our vital energy, enables healing of our body and our relationships, and protects us from epidemics, disease, provocation of energy, hostile forces and disturbing spirits.
