Why do you have to pay off the debts of your previous life in this life?

This is the "karma" power that controls causality. Because heaven and earth are selfless, it shows its fairness and justice. From the microscopic point of view, people's life is a day-to-day life, and the debts owed some time ago are also reasonable in the future. Macro life, just like life in this world. People's birth, illness, death and illness are staged, and life is like a day. Therefore, the debt of the previous life must be paid back in the next life.
