I’m not sure about a specific person named “taoasvi” sharing an experience of Siddhi tap. However, in Jainism there are well-known and authentic explanations about Siddhi Tap and many respected examples of its practice. Here are the core ideas and a commonly shared inspirational view, drawn from Jain texts and traditional understanding:

• What Siddhi Tap means: Siddhi Tap is a stringent austerity aimed at purifying the soul and progressing toward liberation. It often involves periods of fasting, restraint, and controlled conduct to destroy karmas and reduce passions. The aim is spiritual progress and eventually moksha (liberation). This is described in Jain discussions of Siddhi Tap and its significance. ( jainknowledge.com)

• Typical structure of Siddhi Tap (as commonly practiced): It is described as an intense form of discipline, such as alternating fast days and then extended fasts, with careful attention to self-control, detachment, and inner purification. The exact format can vary by community, but the emphasis remains on purifying the soul and strengthening vairagya (detachment). ( jainknowledge.com)

• Why it is esteemed: Practitioners who undertake Siddhi Tap are regarded as exemplars of self-control and spiritual resolve. Their observance is meant to inspire others toward disciplined living and toward purification of karma. This is presented as a central merit of such austere practices. ( jainknowledge.com)
