What is the story of the wealthy man, his wife, and Dubki, and how does it demonstrate the principle of karma?

The story illustrates how actions in one life bear fruit in the next. A greedy, wealthy man deceitfully offered land to Shankara that was actually mortgaged from a poor woman named Dubki. As Chapter 47 explains, this desire for worldly objects is a false trap that leads to destruction. A calamity struck, and the wealthy man, his wife, and Dubki all died. Their karma then unfolded in their subsequent lives. The wealthy man was reborn as Veerabhadra to a poor Brahmin, his pious wife was reborn as Gauri, and Dubki was reborn as a man named Chenbasappa. This demonstrates that their change of state happened because their karma bore fruit, showing the direct consequences of their past actions.
