Not exactly.

In Jain thought, karma bandhan depends primarily on the state of mind, intentions, passions, and violence involved in one’s actions, not simply on whether a person is a trader, farmer, doctor, or monk. So it is not correct to say that trading automatically has the least karma bandhan.

That said, many Jain families historically became traders because:

• trading often involves less direct हिंसा (physical violence) than many other occupations,
• it can be more compatible with ahimsa,
• it may allow a lifestyle that supports religious discipline, restraint, and aparigraha.

So the idea is more about traditionally being considered comparatively less हिंसक than some other professions, not that it has the least karma by itself.

In Jainism, even business can create karma if it involves:

• deceit,
• greed,
• harshness,
• exploitation,
• attachment,
• or indirect harm to living beings.

The lowest karma bandhan is not from a particular profession alone, but from right conduct, self-restraint, and reduced passions. For householders, the goal is to choose work that is less हिंसक and more ethical, while for ascetics, total renunciation is the path.

So the better Jain understanding is:

Many Jains traditionally chose trade because it could support ahimsa and restraint, but it does not automatically mean trade creates the least karma bandhan.
