In Jain tradition, Vidyadhars are a class of beings who are known for their knowledge of vidyas — special sciences, मंत्र, and supernatural powers.

Simple meaning:

• Vidyā = special knowledge or power
• Dhara = one who holds or possesses

So, Vidyadhars are beings who possess extraordinary knowledge and abilities.

In Jain literature:

• They are often described as semi-divine beings living in certain regions, especially in the Vidyadhara lands.
• They are not liberated souls.
• They are still within samsara and subject to karma, birth, and death.
• Some texts describe them as highly skilled, powerful, and spiritually advanced compared to ordinary humans.

Important point:

In Jain Dharma, even very powerful beings like Vidyadhars are not free from karma unless they follow the right path toward ratnatraya: right faith, right knowledge, and right conduct.

If you want, I can also explain the role of Vidyadhars in Jain cosmology.
