In Jain dharma, the best choice is not to lie, and not to speak hurtful truth either. The ideal is:

• Truthful
• Non-violent
• Necessary
• Gentle
• Without deception

So among the three, the Jain approach is:

1. Do not lie — lying creates adharma and bondage.
2. Do not speak truth that needlessly harms — truth should not become cruelty.
3. Choose silence if it avoids harm and does not become deceit — but silence should not be used to trick others.

In simple terms: Satya should be joined with Ahimsa. A statement that is true but painful is not always right to speak. A lie is also not right. So the best is wise, restrained, harmless speech or pure silence when speech would cause injury.

A good Jain principle here is: speak only when it is true, beneficial, and harmless.
