What is "trishala"

Trishala also known as Queen Trishala, Trishala Devi, Priyakarini, or Trishala Mata (Mother Trishala) was the mother of Mahavira, the 24th Tirthankara of Jainism, and wife of the Jain monarch, Siddartha of Kundgraam, of present-day Bihar.

She finds mention in the classical Jain Agamas, the Kalpa sutra, which is primarily a biography of the Tirthankaras.
