Step 1: Understanding the Concept:
Jain Metaphysics defines "existence" or "reality" through a unique triad. This definition, found in Tattvartha Sutra 5.30, reconciles the concepts of change and permanence.
Step 2: Detailed Explanation:
The formula is: Utpāda-vyaya-dhrauvya-yuktaṃ sat.
1. Utpada (Origination): The emergence of a new form or mode (Paryaya). Example: A gold bar is turned into a ring; the ring is the origination.
2. Vyaya (Cessation): The disappearance of an old form. In the same example, the form of the gold "bar" ceases to exist.
3. Dhrauvya (Persistence): The underlying substance remains constant throughout the change. The "gold" itself remains gold, whether it is a bar or a ring.
Jainism argues that reality is not purely permanent (as in some Vedantic views) nor purely momentary (as in Buddhism). It is a combination of both—permanence in substance and change in modes. This is known as the doctrine of Anekantavada applied to metaphysics.
Step 3: Final Answer:
Reality (Sat) is characterized by the simultaneous occurrence of origination, cessation, and persistence.
