Step 1: Understanding the Concept:
The life of a Jain monk is governed by strict ethical codes designed to stop the influx of karma (Samvara). One of the primary classifications of ascetic conduct is the "Thirteen-fold Conduct" (Terahaprakara Charitra).
Step 2: Detailed Explanation:
1. Assertion (A) analysis: In Jain asceticism, the total discipline is often summarized into thirteen points that a monk must strictly follow to ensure non-violence and self-control. This is a standard part of Jain ethics. Thus, (A) is true.
2. Reason (R) analysis: The breakdown of the 13 is as follows:
- 5 Mahavratas: Non-violence, Truth, Non-stealing, Celibacy, and Non-possession.
- 5 Samitis: Carefulness in walking, speaking, eating, handling objects, and disposal of waste.
- 3 Guptis: Control/Restraint of mind, speech, and body.
Summing these up: \( 5 + 5 + 3 = 13 \). These 13 points constitute the fundamental spiritual "armor" of a monk. Thus, (R) is true and correctly defines the components mentioned in (A).
Step 3: Final Answer:
Both (A) and (R) are true, and (R) correctly explains the composition of the conduct mentioned in (A).
