Please follow this instructions for next solar and lunar eclipses:
• If you wish, the Mahima Form can be covered in neem/bilva leaves or a turmeric-dyed cloth during full and partial eclipses. Note that this is not mandatory.
• Soak a clean white cotton cloth in water mixed with turmeric powder. Ensure the cloth is fully dry before placing it on the Mahima Form.
• Afterwards, you can bury or burn the leaves or cloth. If you wish to, you can keep the turmeric-dyed cloth and reuse it for future eclipses. Do not use it for other purposes in between.
• If the eclipse is not visible from your city, you need not cover the Mahima Form.
Please note no damage is caused to your copper form, you can continue the process as usual. Even if there is discoloration.
