Can very old ashes (from years or decades ago) still be immersed at Prayagraj?

Yes. The scriptures do not impose an upper time limit on Asthi Visarjan — ashes preserved for 5, 10, 20, or even 50+ years can be immersed at Prayagraj with full scriptural validity. When significantly delayed, the ceremony is typically combined with Shraddha and Pind Daan to restore the soul’s spiritual balance. Some families bring ashes preserved through generations — grandparents’ or great-grandparents’ ashes that could never be immersed due to partition, war, migration, or other circumstances. Our pandits conduct these multi-generational Asthi Visarjan ceremonies with the proper scriptural procedure, treating them as “combined ancestral liberation” rituals. No judgment, no surcharge for delay — only compassion and complete Vedic observance.
