In Jainism, a Jain should earn a living in a way that minimizes harm to living beings and supports spiritual growth. Key ideas:

• Ahimsa (non-violence) in work: Choose occupations that avoid harming any living beings. Many Jains avoid roles that involve killing or causing suffering to animals (e.g., animal slaughter).
• Truth and integrity: Conduct your work honestly, without deceit or exploitation.
• Non-stealing (asteya): Do not take what is not freely given; earn money righteously.
• Aparigraha (non-attachment): Simple, ethical living; avoid excessive wealth accumulation beyond need, and share resources through charity.
• Responsibility to society: Use earnings for welfare, education, and helping others; support temples, charitable activities, and community service.
• For householders (upāsakas/upāsikas): You may have a wide range of lawful professions, but you should strive to practice restraint and mindfulness—not overindulge in sensual pleasures, and keep dharma as the guide for how you work and spend.

In short: work should be lawful, ethical, compassion-friendly, and pursued with awareness of its impact on all living beings and on your own spiritual progress.
