Answer

In Jain Dharma, Tras kāy means mobile-bodied living beings — souls that have the ability to move from one place to another by their own effort.

Explanation

Jainism classifies living beings into two broad types:

• Sthāvar kāy — one-sensed, immobile beings
• Tras kāy — mobile beings with two or more senses

Tras kāy beings include:

• Two-sensed beings — such as worms, shell creatures
• Three-sensed beings — such as ants, lice
• Four-sensed beings — such as flies, bees
• Five-sensed beings — animals, humans, heavenly beings, hellish beings

They are called “tras” because they can experience fear, pain, and movement more visibly than one-sensed beings.

Spiritual Understanding

The concept of Tras kāy teaches us to be careful in our actions, speech, food habits, and daily life so that we reduce harm to living beings. This supports the Jain principle of Ahimsa — non-violence.

Takeaway

Tras kāy = mobile living beings with two or more senses. Understanding this helps a Jain practice greater compassion and carefulness toward all forms of life.
