Here are simple Jain-focused guidelines about donations in temples that share space with Hindu deities:

• Core principle: Donate with a pure heart (dátā) and aim for welfare (paropakār). In Jain dharma, charity is praised when it helps living beings and sustains righteous activities, regardless of the exact form of worship in the space.

• End-use of donations: If you make a donation to a shared temple, you may specify how you want your funds used (e.g., maintenance of the Jain shrine, charitable activities, education programs, sevas for the needy). If you don’t specify, the governing body should use the funds for overall temple maintenance and for charitable activities that align with the temple’s mission, while respecting all traditions present in the space.

• Respectful conduct: In a shared space, follow decorum appropriate to a Jain shrine (cleanliness, non-violence in actions, no intoxicants on the premises, reverence toward all spiritual symbols, and peaceful behavior). This preserves the sanctity of the Jain part of the space and respects other traditions there.

• Clarity and transparency: Prefer temples with clear governance and transparent accounting. Request regular reports on how donations are used and ensure records exist for Jain-related programs and maintenance.

• Autonomy of the Jain tradition: Donations to the Jain portion of a shared temple should enable Jain religious activities, education, and community support, while not interfering with Hindu worship or practices in the same space.

• Practical approach if there’s disagreement: If you have concerns about how funds are allocated, discuss with temple trustees or management. Jain ethics emphasize honesty, restraint, and benevolence; seek solutions that promote welfare for all without compromising Jain principles.
