Answer

In Jain practice, it is best to drink properly boiled water, not just hot water from a water can.

Explanation

In Jain Dharma, water is boiled to reduce harm to tiny living beings present in water. Simply taking hot water from a water can may not be enough, because:

• It may only be heated, not fully boiled.
• It may not have reached proper boiling temperature.
• It may have been stored for an unknown time.
• It may have been refilled or exposed again.

Traditionally, Jain households boil water properly, cool it if needed, and then use it within the accepted time limit according to their tradition and guidance from elders or monks.

Spiritual Understanding

The purpose is not merely to drink warm water, but to follow ahimsa carefully by minimizing harm to water-bodied and microscopic living beings as much as possible.

Takeaway

For Jain observance, use properly boiled water rather than just hot water from a can, unless you are certain it was properly boiled and stored according to Jain practice.
