In Jainism, Siddhi Tap is considered a very rigorous and auspicious penance, and performing 17 Ayambil (a special kind of fasting where only simple, tasteless food is eaten once a day) as part of this tap is highly venerated.

According to Jain tradition, Acharya Shri Jayantsen Surishwarji Maharaj is notably recognized for completing 17 Ayambil as part of Siddhi Tap. Many other eminent Acharyas and Munis have also undertaken this tapasya, but Jayantsen Surishwarji is especially remembered in recent times for performing this challenging penance.

It is important to note that in Jain history, numerous monks and devotees have undertaken Siddhi Tap and similar austerities as a means of spiritual purification and self-discipline, following the examples set by ancient Jain Acharyas and Tirthankaras.

If you are seeking a historical or specific reference from Jain scriptures, Siddhi Tap and the practice of multiple Ayambils are described in various Jain texts as being performed by advanced sadhus (monks) and sadhvis (nuns), but individual names may vary depending on the tradition and sect. Acharya Jayantsen Surishwarji is a respected example in contemporary Jain practice.
