About Āchārya Siddhasen Divakar’s sister, the Jain historical texts simply mention that:

• He had a sister who was a Jain sadhvī (nun).
• She was very intelligent and spiritually advanced.
• In one famous incident, she correctly completed a verse about Siddhasen Divakar, which showed her deep understanding.

However, her personal name is not clearly given in the traditional Jain sources that narrate his life. So, based on available authentic Jain literature, we do not know her name with certainty.
