Deshna
A Deshna is a type of religious speech in Prakrit. According to Jainism, after a Tirthankara gains infinite knowledge, in his honor, the heavenly beings create a place called samavasarana, where all creatures are welcomed (including non-human creatures, humans, and angels) for Tirthankara's speech. This speech is understood by everyone in their own languages. These types of speeches are known as deshnas.
