In Jainism, right speech (Samyak Vachan) is an important aspect of ethical conduct. Jain teachings encourage speaking truthfully, kindly, and only when necessary, avoiding gossip, harsh words, or falsehood. Choosing not to speak with someone is not inherently wrong in Jainism, especially if speaking might lead to conflict, harm, or violation of one's principles.

Jain monks and nuns often observe silence (mauna) as a practice to control speech and avoid unnecessary harm through words. Lay followers may also observe periods of silence for spiritual discipline.

However, if deliberately ignoring or refusing to speak with someone arises from anger, pride, or to cause hurt, this could be considered contrary to the principles of ahimsa (non-violence) and aparigraha (non-attachment). Jainism teaches to act with compassion, understanding, and non-violence in all interactions.

Ultimately, the intention behind not speaking is important. If it helps maintain peace, self-control, and non-violence, it can be justified. If it leads to harm or is driven by negative emotions, it should be reconsidered.
