In Jainism, the principal taught to manage and earn wealth is called Aparigraha (non-possessiveness or non-attachment). Jain teachings emphasize that while it is acceptable to earn wealth through honest and righteous means (right livelihood or Samyak Livelihood), one should not become attached to possessions or accumulate wealth beyond one’s needs.

Key guidelines for managing and earning wealth in Jainism include:

1. Earn Rightly (Samyak Livelihood): Wealth should be earned by honest, ethical, and non-violent means, avoiding professions or businesses that cause harm to any living being.
2. Limit Possessions (Parigraha Parimana Vrata): Lay followers (Śrāvakas) are advised to voluntarily limit their possessions, including money, property, and material goods, to prevent greed and attachment.
3. Charity (Dāna): A portion of one’s wealth should be used for charitable purposes, especially supporting the needy, religious activities, and the welfare of all beings.
4. Contentment (Santosha): Be content with what one has, and avoid excessive desires and accumulation.

Through these principles, Jainism teaches that wealth should be used as a means to support a righteous life, help others, and ultimately progress on the path of spiritual liberation.
