Wachirayan also led a reform in Buddhist education, mainly by writing new textbooks for the study of Pali (in six volumes), known as the "Bali Waiyakon", which provided an easier way to learn Pali than the traditional grammar books. Wachirayan also wrote some other influential Thai Buddhist doctrinal works, including "Phuttasasana Suphasit" (Selected Buddhist proverbs), "Phutthaprawat" (Life of the Buddha), and "Winayamuk" (Entrance to the Vinaya). He also established "Dhammacakṣu", the first Buddhist journal in Siam. Due to his extensive scholarly achievements, Prince Wachirayan has been called "the leading intellectual of his generation in Siam" by historian David K. Wyatt. Because the prestigious state examinations relied mainly on Prince Wachirayan's works, his doctrinal interpretations became the orthodox doctrine of official Thai Buddhism. The new examinations and curriculum eventually spread throughout the provinces. The prince sent learned monks to the provinces to promote the new education system.
