In Jainism, visiting a temple is voluntary, not mandatory. People may choose not to go for various personal or spiritual reasons, such as:

• Observing strict vows, penance, or prolonged meditation (svādhyāya, samayik, or ekaṅkāra) that keeps one focused away from external rituals.
• Illness, old age, or physical weakness that makes temple visits difficult.
• A desire to cultivate inner conduct and right faith directly, rather than relying on external places of worship.
• Specific personal vows or spiritual disciplines that call for staying in one place or engaging in private puja and reflection.

The core aim in Jain practice is to cultivate samyak darshan (right faith), samyak jnana (right knowledge), and samyak conduct. Temples serve as supportive spaces, but they are not the essence of Jain practice.
