Hi Dawnfirstlight and Realisation,
If i'm not wrong, and i may be wrong here, the article referred
to is referring to the short Vajrasattva mantra.
It is said that one may have created the karmas of slandering
the dharma unknowingly as it is a very easy karma to create or the
five uninterrupted karmas from past (lives) etc which will stop you
from taking rebirth in pureland. So it is impt to recite the short
vajrasattva mantra 400,000 with the four powers to purify this
negative karma.
His Holiness Jigme Phuntsok revealed a practice that one can use
to recite this 400,000 mantras.
What is Vajrasattva mantra in Chinese ? Thanks.
