Because of the negative actions that we have created in the past under the influence of deluded minds we now experience suffering and problems, as well as difficulties in developing faith and conviction in spiritual practice and in making progress on the path to enlightenment. But no matter how negative our mind is we have the opportunity to purify it completely by engaging in purification, the root of future happiness and spiritual realizations. One of the most powerful purification practices is the Mahayana Sutra of the Three Superior Heaps, also known as The Bodhisattva's Confession of Moral Downfalls. In this practice, we visualize the Thirty-five Confession Buddhas and practise purification in their presence. Through the power of their blessings and prayers, we can swiftly purify even the heaviest negative actions simply by faithfully reciting their names. This booklet contains a brief explanation of the practice.
