In Jainism, Divya Dhwani refers to the "divine sound" or "celestial discourse" that is believed to emanate from the Tirthankaras (spiritual victors) when they attain omniscience (Kevala Jnana). According to Jain beliefs, after attaining Kevala Jnana, a Tirthankara delivers sermons for the benefit of all living beings. This sermon is not spoken in any particular language but manifests as a divine sound—Divya Dhwani.

Key points about Divya Dhwani in Jainism:

• Universal Comprehension: The Divya Dhwani is understood by every listener in their own language, regardless of their background or species. This signifies the universality of the Tirthankara's message.
• No Use of Physical Speech: The Tirthankara does not use vocal cords or physical speech; the knowledge flows naturally in the form of this divine sound.
• Samavasarana: The Divya Dhwani is especially associated with the Samavasarana, the divine preaching assembly formed when a Tirthankara attains omniscience. All beings, from humans to animals and celestial beings, gather to listen to this discourse.
• Scriptural References: Jain scriptures such as the Kalpa Sūtra and other Agamas describe the phenomenon of Divya Dhwani and its significance.

Thus, Divya Dhwani represents the pure and universal transmission of spiritual knowledge by a Tirthankara, ensuring that the teachings are accessible to all sentient beings.
