MahaSatipatthana Sutta: Great Discourse on Four-Fold Establishment of Mindfulness is written by Bro James Ong. This book describes Satipatthana, or mindfulness practice, by referring to this Discourse which the Buddha first delivered to the Kurus people. As a result, we return to the Buddha's core orthodox Discourse as a guide. You will obtain a thorough knowledge of what the Buddha truly taught in this manner. You can also see if you're on the correct track or if there's anything lacking from your routine that you should add.
