Why can Asoka's history be discribed as written in stone?

Asoka's history can be described as "written in stone" due to his extensive use of rock edicts and inscriptions to communicate his policies and beliefs. These inscriptions, carved on pillars and boulders throughout his empire, served to disseminate his messages of non-violence, moral governance, and Buddhism to a wide audience. The durability of stone ensured that his ideas would endure over time, allowing them to influence future generations. This method of documentation highlights Asoka's commitment to transparency and his desire for a lasting legacy.
