Vajira.

About Vajira

Vajira, a Buddhist nun mentioned in the Samyutta Nikaya (I.134-55), is one of the earliest women adepts in Buddhist history. She was confronted by Mara while meditating and asked about the origin and creator of her "Being", i.e., her soul. She responded by comparing one's "Being" to a chariot, showing that it had no permanent existence but was made up of constituent parts.
