Khenpo Sodargye
HH Jigme Phuntsok Rinpoche once said, “The King of Prayers perfectly possesses the four causes for taking rebirth in Sukhavati. If you recite this aspiration prayer once during each class, it is the supreme method for accumulating the merits to take rebirth in Sukhavati.”
Note: Four causes for taking rebirth in Sukhavati
(1) Visualizing Amitabha and the pureland
(2) Generating Bodhichitta
(3) Accumulating merits and purifying obscurations
(4) Making pure aspirations and dedicating merits to take rebirth in Sukhavati
