Answer

According to Jain Dharma, the loka is not only on Earth. It is the entire inhabited universe described in Jain cosmology, and Earth is only one small part of it.

Explanation

Jain teachings describe the cosmos as having:

• Urdhva Loka — upper worlds
• Madhya Loka — middle world, where humans live, including Earth
• Adho Loka — lower worlds

So, other realms do exist, but they are not visible to ordinary eyes. They are not “on Earth hidden somewhere”; rather, they are different regions of the Jain universe.

Beyond loka, Jainism also describes Aloka, which is the space outside the universe. In Aloka, there is only empty space—no world, no beings, no movement of matter as we understand it.

Spiritual Understanding

This teaching shows that Jain cosmology is vast, structured, and purposeful.

• Earth is only one small part of existence.
• Souls can be born in many realms according to karma.
• The universe is not unlimited in Jain thought; it is finite.
• Liberation means rising beyond all these realms to the state of moksha, above the loka.

Takeaway

In Jainism, lokas are not only on Earth. Earth is part of the middle world, while other realms exist in the same cosmic structure but are not visible to ordinary perception.
