Answer

Yes, a Jain can visit a Hindu temple, including temples of Lord Shiva, Hanuman ji, or Maa Adishakti, if it is done respectfully and without violating Jain principles.

Explanation

From the Jain point of view:

• Jain Dharma does not forbid entering another temple.
• But the central Jain devotion is toward the Pancha Parmeshthi:

- Arihant - Siddha - Acharya - Upadhyaya - Sadhu

• So a Jain may go to a Hindu temple:

- for respect - for family or social reasons - for peace and prayer - to observe, not to perform practices that conflict with Jain values

A Jain should avoid anything that goes against Jain vows, such as:

• violence or harmful offerings
• rituals involving animal sacrifice
• any act that disturbs ahimsa, purity, or inner restraint

Spiritual Understanding

In Jain Dharma, the main focus is on:

• Ahimsa — non-violence
• Aparigraha — non-attachment
• Samyak Darshan — right faith
• inner purification

So visiting another temple is not the main issue; the important thing is whether your action supports or weakens your Jain way of life. A Jain can show respect to others, while still keeping firm faith in Jain principles.

Takeaway

A Jain may go to Hindu temples respectfully, but should remain true to Jain vows and avoid any ritual that goes against ahimsa or Jain faith. If you want, I can also explain this from the perspective of Digambar and Shwetambar traditions.
