In Jainism, Chaud Purvi Tap (also spelled as Chaud Purvi Tap or Chaud Purvi Tapa) refers to a highly rigorous ascetic practice of fasting. The term is derived from:

• Chaud: Fourteen,
• Purvi: Refers to ancient Jain scriptures or canonical knowledge,
• Tap: Austerity or penance.

However, more specifically, in the context of ascetic practices, Chaud Purvi Tap is interpreted as a form of fasting for fourteen days continuously without food (and often with only boiled water, depending on the tradition). This is one of the most intense and revered austerities undertaken by Jain monks, nuns, and sometimes even by highly devoted laypersons (Shravaks and Shravikas) with proper guidance.

Importance in Jainism

1. Spiritual Merit: Performing Chaud Purvi Tap is believed to help in the destruction of karmas (bad deeds) and aids in spiritual purification.
2. Self-Discipline: It demonstrates supreme self-control, detachment, and renunciation, which are central virtues in Jainism.
3. Historical Example: Many Jain Tirthankaras, saints, and monks have undertaken such tapasya as described in Jain scriptures.

Process

• The aspirant fasts for fourteen consecutive days.
• During this period, no solid or liquid food is consumed. Only boiled water (and that too only during daylight hours, if at all) may be permitted.
• The austerity is often concluded with a ritual called Parna, where the fast is broken under specific religious protocols.

Scriptural Reference

While the exact term “Chaud Purvi Tap” may not be found in the earliest Jain Agamas, descriptions of long fasts (upvas) and austerities are present throughout Jain literature, especially in the lives of Tirthankaras and prominent ascetics.

Caution

Such an austerity is extremely demanding and should only be undertaken with full understanding, proper health, and under the guidance of experienced Jain monks or scholars.
