Reverberation
Relics, in current Buddhism, actually had a definition.
After the eminent monks passed away, the hair, bones, and ashes left by them became relics.
After the spark, the resulting crystals were called relics or solid seeds.
As the times changed, high-tech methods were emerging one after another. Buddhism's perception of relics had also changed greatly.
Some people believed that relics were only material elements and had no spiritual elements. The main reason why believers respected relics was that they hesitated to gather the merits, compassion, and wisdom of the great monks in his lifetime.
But this perception was not accurate.
What was the meaning of relics? The higher status of a monk, the more he understood it.
For example, Master Yi Deng.
