Answer

Yes, a person can go to a Jain mandir wearing black. There is no universal Jain rule that absolutely forbids entering a mandir in black clothes.

Explanation

In Jain Dharma, the more important things when going to mandir are:

• Clean clothes
• Respectful and modest dress
• Purity of body and mind
• Devotional attitude
• Non-violence and humility in behavior

Some families, communities, or local traditions may prefer white, light-colored, or simple clothes for puja because they symbolize purity, peace, and simplicity. In some places, black may be avoided due to cultural beliefs, not because of a strict Jain scriptural prohibition.

Spiritual Understanding

Jain Dharma gives more importance to inner purity than outer color. If your mind is filled with reverence, humility, and devotion toward Arihant Bhagwan, that is more important than the color of your clothing.

Takeaway

You may go to mandir wearing black, but if your local mandir or family tradition avoids black, it is respectful to follow that custom.
