What is the main idea of Jainism?

-compassion of the Buddha
-nonviolence to all life
-silence and stillness during winter
-knowledge is key to nirvana

The main idea of Jainism is nonviolence to all life.

The main idea of Jainism is nonviolence to all life. Jainism emphasizes the importance of respecting and not causing harm to all living beings, including humans, animals, and even plants. This principle of nonviolence, known as ahimsa, is central to Jain philosophy and guides followers in their ethical behavior and decision-making. While knowledge is indeed a key aspect of Jainism, the central theme revolves around practicing nonviolence and compassion towards all forms of life. Silence and stillness during winter and the concept of nirvana are not directly related to the main idea of Jainism.

The main idea of Jainism is nonviolence to all life. To arrive at this answer, one can look at the options given and analyze each one.

- "Compassion of the Buddha" doesn't accurately represent the main idea of Jainism, as Jainism predates Buddhism and has a distinct set of teachings.
- "Silence and stillness during winter" does not relate to the main idea of Jainism.
- "Knowledge is key to nirvana" is not correct because Jainism teaches that nonviolence, not knowledge, is the pathway to liberation.

Therefore, the correct option is "nonviolence to all life." Jainism emphasizes the importance of practicing ahimsa, which means avoiding harm, violence, and cruelty to all living beings. This principle extends beyond humans to include animals and even the smallest insects.
