We respectfully and gratefully acknowledge the support and counsel of Dharma Master Lok To, Master Thich Phuoc Bon and Rev. K. Watanabe, along with the helpful comments and suggestions of Upasaka Hien Mat (who gladly reviewed this entire book in less than a ksana!), Upasaka Minh Con and Upasaka Sean Everett. Special mention is due to Upasaka Thieu Chuu, who through his own vernacular translation of this commentary more than half a century ago, clarified many difficult passages and transcendental points of Dharma. Without their invaluable contributions, this book would not have been possible.
