Answer

In Jain practice, you do not need to add chuna (lime/calcium hydroxide) to drinking water.

For drinking water, the traditional Jain emphasis is on:

• Filtering water properly
• Using boiled water where followed according to family or sect practice
• Consuming water within the proper time limit as observed in your tradition
• Minimizing harm to water-bodied living beings

Explanation

In Jain Dharma, water is understood to contain subtle living beings. Therefore, care is taken before drinking or using water.

Adding chuna is not a general requirement for Jain water practice. In fact, chuna is a strong alkaline substance and should not be added to drinking water unless there is a specific, knowledgeable reason and proper guidance.

Spiritual Understanding

The Jain purpose is not merely a physical purification process, but the practice of ahimsa, awareness, restraint, and carefulness in daily life.

The focus should be on drinking water in a way that reduces violence as much as possible, according to accepted Jain practice.

Takeaway

No, adding chuna to drinking water is not necessary in Jain Dharma. Follow proper Jain methods of filtering and, where practiced, boiling water.
