The purification practice of the Mahayana Sutra of the Three Superior Heaps
In our previous lives, while under the influence of deluded minds, we created a great deal of negative karma, and we also transgressed our commitments and incurred root and secondary downfalls. As a result we now experience difficulties in developing faith and conviction in Dharma, and in making progress on the stages of the path to enlightenment. Moreover, if we do not purify all this negativity while we have the chance we shall have to experience great suffering in the future.
Any living being, even a worm or an insect, can commit negative actions, but only humans have the fortune to be able to purify them. We have been accumulating non-virtuous actions and experiencing their suffering results since beginningless time, but we now have the opportunity to purify them completely. We should make use of this precious opportunity to purify our negative karma, not to create more! Since purification is the root of future happiness and spiritual realizations we should strive to cleanse our mind of delusions and negative karma.
One of the best methods for purifying negativities and downfalls is the Mahayana Sutra of the Three Superior Heaps, otherwise known as The Bodhisattva’s Confession of Moral Downfalls, or the Bodhisattva Mahayana Confession Sutra.
This sadhana contains the root text of the Sutra and a short explanation of the practice.
A more detailed explanation of this practice can be found in the book, The Bodhisattva Vow.
