The first meeting of Ghosal with Mahavir Swami was held at Nalanda. Parsva, the traditional predecessor of Mahavira is the first Jain figure for whom there is reasonable historical evidence. He might have lived somewhere in the 9th-7th century BCE. Flowers of Parsva are mentioned in the canonical books; and a legend in the Uttaradhyayana sutra relates a meeting between a disciple of Parsva and a disciple of Mahavira which brought about the union of the old branch of the Jain church and the new one.
