Answer

In Jain practice, boiled water should be cooled down before filling it into a bottle and also should be cool enough before drinking.

Do not pour very hot boiling water directly into a bottle, especially a plastic bottle.

Explanation

In Jain Dharma, boiling water is commonly done to reduce living organisms in water and to support the practice of ahimsa. After boiling:

• Let the water cool naturally in a clean vessel.
• Once it becomes reasonably cool, fill it into a clean bottle.
• Drink it only after it is safe and comfortable to drink.

Traditionally, boiled water is also used within a proper time limit, which may vary by Jain tradition and local practice. Many Jain families follow guidance from their guru or sampradāya regarding how long boiled water may be used.

Spiritual Understanding

The main intention is carefulness, cleanliness, and ahimsa. Boiling water is not only a health habit in Jain life; it is connected with awareness toward even subtle forms of life.

Takeaway

Boil the water, let it cool in a clean covered vessel, then fill it into a clean bottle and drink it when it is comfortably cool.
