The Simsapa plugin integrates with Obsidian to provide powerful Pāli dictionary and sutta lookup features. It requires the Simsapa Dhamma Reader app to be running in the background, allowing users to search and retrieve definitions from Pāli dictionaries directly within Obsidian. By double-clicking a word in a note, users can instantly access its meaning, with results displayed in the sidebar or in a separate lookup window. This plugin enhances the reading and study experience for users interested in Pāli texts and Buddhist teachings, making it easier to reference and understand key terms.
