A millionaire Sudatta was the wealthiest person in India who built the Jeta Grove Monastery for Śākyamuni Buddha. However, the temple vanished without a trace in a fire. Originally, this wealthy man made his fortune through a fish-killing business. Because of this, the temple disappeared completely.
Likewise, meritorious good acts of people these days seem great in all appearances. When we inquire about their source of revenue, however, we learn that it was either from a domain granted for a glorious achievement in war or savings made by torturing people without a cause. They may look like great acts of charity (fuse) in Buddhism, but because their acts are not pure at the root, they are not only unable to attain Buddhahood, but they also cause their descendants to vanish without a trace.
