In addition to the above works, I have also consulted many previous English translations and renderings of the Dhammapada, complete and incomplete, including those by Ven. Ananda Maitreya, Babbitt, Beyer, Ven. Buddharakkhita, Byrom, Cleary, Kaviratna, Vens. Khantipalo and Susañña, Mascaro, Ven. Narada, Ven. Piyadassi, Radhakrishnan, and Wannapok, as well as Thai translations by Plengvithaya and Wannapok. In addition, I have consulted translations of the Udanavarga -- again, complete and incomplete -- by Sparham and Strong. I have also drawn from the Royal Thai Edition of the Pali Canon, published by Mahamakut Rajavidalaya Press, Bangkok, 1982.
