Answer

The greatest guiding commandment in Jainism is:

Ahimsa Paramo Dharma Non-violence is the supreme religion/duty.

Explanation

In Jain Dharma, Ahimsa means not harming any living being through:

• Thought
• Speech
• Action

Jainism teaches that all living beings have a soul, and every soul desires happiness and freedom from suffering. Therefore, one should live with compassion, carefulness, restraint, and respect toward all forms of life.

Spiritual Understanding

Ahimsa is considered supreme because violence binds harmful karma to the soul, while non-violence purifies the soul and leads one toward liberation.

For monks and nuns, Ahimsa is practiced in the highest and strictest form. For householders, it is practiced according to their capacity through vegetarianism, compassion, truthfulness, self-control, and careful living.

Takeaway

In Jainism, the highest commandment is to live in a way that causes the least harm and cultivates the deepest compassion for all living beings.
