These inscriptions were meant to convey Ashoka's messages to his subjects and future generations, making them reliable sources for studying his reign.

2. Multilingual nature:

This multilingual approach suggests his efforts to communicate with diverse populations within his empire. The inscriptions in different languages allow scholars to compare and analyze the content, providing a comprehensive understanding of Ashoka's policies and religious beliefs.

3. Edict format:
Ashoka's inscriptions follow a consistent format known as the edict format. These edicts often begin with Ashoka's royal title and provide instructions, proclamations, and moral teachings. They cover a wide range of topics such as social welfare, religious tolerance, and ethical conduct. The edict format allows researchers to compare and contrast different inscriptions, identifying Ashoka's evolving policies and priorities.

4. Geographical distribution:
Ashoka's inscriptions are found in various regions, including present-day India, Nepal, Pakistan, and Afghanistan. The widespread distribution of these inscriptions indicates the extent of Ashoka's empire and his efforts to disseminate his messages across different territories. By studying the geographical distribution of inscriptions, historians can trace the expansion and administration of the Mauryan Empire.
