Udyana, known today as Swat Valley in Pakistan, was once a prominent Buddhist region that played a vital role in the development of early Buddhism. The name "Udyana" translates to "garden" or "orchard" in Sanskrit, reflecting the area's lush landscapes and rich history. It's believed that Udyana supported around 500 Sthavira Buddhist monasteries, which provided lodgings and sustenance for traveling monks for three days. Prakrit was the language spoken here, highlighting its cultural significance.
