After cremation, ashes (asthi) are treated with reverence and disposed of in a way that supports the departed soul, commonly by immersion in flowing water or by placing them in the earth to dissolve gradually. The key is to do it with respect and detachment, keeping the focus on the soul’s welfare rather than on ritual excess. There can be small differences between Digambar and Śvetambar communities in the exact sequence, but both traditions generally follow cremation and a respectful disposal of the asthi. If you’re planning a ceremony, consult your local Jain temple or elder to follow your lineage’s customs. You can read more here and here .
