Answer

If someone drinks cold water by chance during tapasya, then the effect depends on the specific vow or rule of that tapasya.

In Jain Dharma, tapasya is based on self-discipline, awareness, and intention. If the water was taken accidentally, without desire or carelessness, it is generally treated differently from knowingly breaking the vow.

Explanation

During tapasya, a person usually follows certain rules, such as:

• Not eating food
• Drinking only boiled water
• Drinking water only at proper time
• Avoiding cold or unboiled water

If cold tap water was drunk:

• By mistake: One should sincerely do pratikraman and ask forgiveness.
• Due to carelessness: One should reflect and become more careful.
• Knowingly: The tapasya may be considered broken according to the rule taken.

Spiritual Understanding

Jain Dharma gives great importance to bhav — inner intention. A mistake made unknowingly should not lead to guilt, but it should lead to more awareness.

The right response is:

• Accept the mistake calmly
• Do micchāmi dukkaḍaṁ sincerely
• Continue with humility if your guru or elder allows
• Consult a knowledgeable Jain sadhu, sadhviji, or respected elder for the exact rule

Takeaway

If cold water was drunk accidentally during tapasya, do not panic. Do sincere repentance, become more careful, and follow the guidance of your guru or knowledgeable Jain elder.
