Answer

In Jain Dharma:

• Those who live in Moksha are called Siddhas.
• Those who live in Dev Lok are called Devas or Devatās.

Explanation

• Moksha is the state of complete liberation, where the soul is free from karma, birth, and death. A liberated soul is known as a Siddha.
• Dev Lok is the heavenly realm where celestial beings reside. They are called Devas.

Spiritual Understanding

• Siddhas represent the highest spiritual state in Jainism.
• Devas enjoy a celestial life, but they are still within संसार and are not liberated yet.

Takeaway

So, the correct terms are:

• Moksha = Siddhas
• Dev Lok = Devas
