The Open Buddhist University
The Open Buddhist University was created with a mission to provide a free, English-language curriculum in Buddhist Studies from the perspective of “Early Buddhism.” This online learning platform has been run by Khemarato Bhikkhu, an American monk in the Thai Tradition, and is based on Khemarato Bhikkhu’s personal library on Google Drive which he shared publicly after his ordination in Thailand in 2019.
The website currently offers 16 courses on the fundamentals of Buddhism, including Buddhism 101, The Practice of Buddhism, Buddhism as a Religion, The Buddha's Words, An Introduction to Buddhist Philosophy, Buddhist Ethics, The Buddha, Imagery in the Early Buddhist Texts, The Majjhima Nikāya, The Aṅguttara Nikāya, Tranquility and Insight, Nibbāna: The Goal of Buddhist Practice, Nibbāna: The Mind Stilled, The Pāli Language: Level 1&2, and Chinese Buddhist Writing. Although none of the courses offer degrees or certificates, they are still great resources for you to learn more about Buddhism online.
The Open Buddhist University also offers helpful external courses for members who have finished the site's course, such as Shin Buddhism in Modern Culture (A short, interactive overview of Jodo Shinshu, from Shinran's life to Japanese Buddhism in the modern United States), The Arahant and the Four Noble Truths (The course about the Venerable Arahants at the time of the Buddha), and many more.
Especially, The Open Buddhist University partners with SuttaCentral to let their students connect and discuss through a Discuss and Discover forum that can be accessed from both websites. Moreover, If you have any feedback or questions, connect to Khemarato Bhikkhu himself at the email at the bottom of the page.
