Answer

Yes, in Jain Dharma this is a meaningful and disciplined niyam:

• Drinking only filtered water
• Not drinking water after sunset
• Not eating food after sunset

This reflects the Jain values of ahimsa, self-control, and carefulness in daily life.

Explanation

In Jain practice, water is traditionally filtered to avoid harming tiny living beings that may be present in it. Avoiding food and water after sunset is also observed because visibility is reduced at night, and there is greater care required to avoid harm to subtle life forms.

This type of niyam helps a person become more mindful of:

• What they consume
• When they consume it
• How much discipline they maintain
• How carefully they live according to ahimsa

Spiritual Understanding

Such a niyam is not only about food and water. It trains the mind to reduce attachment, control desires, and live with greater awareness. Even a small daily discipline, when followed sincerely, becomes a step toward inner purity.

Takeaway

Your niyam is spiritually valuable. Follow it with humility, consistency, and awareness of ahimsa. If health concerns arise, especially regarding water, it is wise to take guidance from a knowledgeable Jain elder or guru.
