Answer

In Jain practice:

• Atham means doing upvas for three continuous days.
• Dubli Atham means doing a lighter form of Atham, where the austerity is reduced compared to full Atham.

Explanation

Atham is a stronger tapasya. Traditionally, it refers to fasting for three days continuously, usually taking only boiled water during permitted hours, according to one’s tradition and health.

Dubli Atham literally suggests a “weaker” or “lighter” Atham. In common usage, it usually means that instead of a complete three-day upvas, the person observes a modified form, such as taking limited simple food or following a less intense fasting rule as guided by elders, family tradition, or a Jain sadhu/sadhvi.

The exact practice of Dubli Atham can vary by region, family, and Jain tradition.

Spiritual Understanding

Both practices are forms of tapasya. Their purpose is not merely physical fasting, but:

• reducing attachment to food,
• strengthening self-control,
• purifying the mind,
• and progressing toward inner discipline.

Takeaway

Atham is the full three-day fast. Dubli Atham is a lighter or modified version of Atham. The exact rules should be followed according to one’s Jain tradition and with proper guidance.
