In Jainism, Bhadratapa (also spelled Bhadratap or Bhadra Tap) refers to a specific type of austerity (tap) or religious penance undertaken by the followers to purify the soul and accumulate spiritual merit. The word itself combines "Bhadra" (meaning auspicious or noble) and "Tap" (austerity or penance).

Bhadratapa is not a standard term found in the canonical Jain scriptures, but in some Jain communities, especially among Shwetambar Jains, it is known as a set of auspicious penances performed for spiritual benefit. Sometimes, Bhadratap may refer to a specific sequence of fasting days or a particular mode of observing austerity, often involving a combination of partial fasting (upvas), complete fasting (nirjal upvas), or other forms of self-discipline.

Purpose of Bhadratap:

• To purify the soul (atman) by reducing the accumulation of karmas.
• To cultivate virtues like self-restraint, patience, and detachment.
• To seek spiritual upliftment and auspiciousness.

Common Practices:

• Observing fasts on specific days.
• Increased devotion, prayer, and meditation.
• Limiting intake of food, or abstaining from food and water for a period.
• Engaging in charitable acts and non-violence (ahimsa).
