Answer

Chhatth Atam Tapasya is a Jain austerity involving fasting practices connected with Chhatth and Attham.

In common Jain usage:

• Chhatth means fasting for two continuous days.
• Attham means fasting for three continuous days.
• Tapasya means spiritual austerity performed for purification of the soul.

So, Chhatth-Attham Tapasya generally refers to the practice of doing such multi-day fasts with religious discipline, devotion, and self-control.

Explanation

In Jain Dharma, fasting is not merely about not eating food. It is meant to reduce attachment to the body, control desires, and focus the mind on the soul.

During such tapasya, a person usually observes:

• Fasting according to their capacity and guidance
• Samayik, Pratikraman, or other religious practices
• Chanting of Navkar Mantra
• Avoidance of anger, pride, deceit, greed, and worldly distractions
• Greater focus on forgiveness, humility, and inner purity

Spiritual Understanding

The true purpose of Chhatth Atam Tapasya is atma-shuddhi — purification of the soul.

Jain Dharma teaches that tapasya helps weaken karmic bondage when performed with:

• Right faith
• Right knowledge
• Right conduct
• Humility and non-attachment

It should not be done for pride, show, competition, or praise.

Takeaway

Chhatth Atam Tapasya is a Jain fasting austerity involving two-day and three-day fasts, practiced with devotion, discipline, and the aim of reducing attachment and purifying the soul.
