“This is the difference between someone whose heart is purified and sound and one whose heart is impure and corrupt. Impure people oppress, and the pure-hearted not only forgive their oppressors, but elevate them in status and character. In order to purify ourselves, we must begin to recognize this truth. This is what this book is all about — a book of self-purification and a manual of liberation. If we work on our hearts, if we actually implement what is suggested here, we’ll begin to see changes in our lives, our condition, our society, and even within our own family dynamics. It is a blessing that we have this science of purification, a blessing that this teaching exists in the world today. What remains is for us to take these teachings seriously.
