Step 1: Understanding the Concept:
The Tirthankaras do not preach for fame but for the welfare of all beings. To ensure that everyone—from scholars to common laborers—could understand the path to liberation, they chose the languages spoken by the masses rather than elite scholarly languages like Sanskrit.
Step 2: Detailed Explanation:
1. Assertion (A) analysis: Lord Mahavira’s sermons are recorded in the Agamas in the Ardhamagadhi dialect of Prakrit. This dialect is often called the "language of the gods" in Jain texts because of its divine origin from the Samavasarana. Thus, (A) is true.
2. Reason (R) analysis: During the 6th century BC, Prakrit was the language of the common people in the Magadha region. By preaching in this language, Lord Mahavira ensured that his message of Non-violence (Ahimsa) and non-possession could reach everyone regardless of caste or education level. This deliberate choice for accessibility is the reason for the language selection. Thus, (R) is true and explains (A).
Step 3: Final Answer:
Both (A) and (R) are true, and (R) is the logical explanation for (A).
