Please note: The specific names of the 24 Tirthankaras of the previous cycle are not always the same as this cycle (our current Avasarpini), and traditional scriptures mention that only the first and last Tirthankaras' names are the same in every cycle (i.e., Rishabhnath and Mahavir). For the past cycle, the first Tirthankara is often referred to as "Kevalinath" or "Kevali Bhagwan" in Jain texts.
