Dzigar Kongtrul Rinpoche (one of Pema Chodron’s teachers) writes:
The gap between ourselves and the Buddhas and Bodhisattvas exists because of our own denial, that could not be penetrated by any blessings. But that denial comes from and covers, deep down, a lack of harmony with oneself, a conflict inside, between how things are and how they appear. Having these two in harmony is enlightenment. As we confess, we feel the lack of the aggression and rejection that underlies our denial. A little white light opens up in our being that one day can expand to the vastness of the sky. We can avail ourselves of help from which we were previously blocked. This is why honest and intelligent confession practice is so valued by many religious traditions.
