How can you know if a person was predestined friends with himself in his last life?

There must be a source. "If there is no debt, how can we meet?" In fact, this is how Buddhism views the relationship between husband and wife, children, men and women and friends. Buddhism found that the relationship between family, husband and wife, children, relatives and friends, and lovers in this life had great karma in previous lives. Being together generally belongs to the following three relationships:

1. To repay kindness: to be harmonious and beautiful with each other and to love each other is to repay kindness to each other;

2. Come to collect debts: quarrel with each other, and the contradictions are constant, but they don't leave. This is mutual debt collection;

3, debt repayment: the relationship between each other is cold and faint, making do with life, this is debt repayment.

So when the debt is paid off and there is no concern for each other, we will separate, and then we will continue the next fate. Therefore, Buddhism does not teach you persistence, but teaches you to live in the present, without fetters, persistence and nostalgia.
