There is a series of spiritual, or supernatural beliefs regarding fortune. These beliefs vary widely from one to another, but most agree that luck can be influenced through spiritual means by performing certain rituals or by avoiding certain circumstances.

Abrahamic religions believe God controls future events; belief in luck or fate is criticised in Book of Isaiahchapter 65, verses 11-12:

What will happen to you for offering food and wine to the gods you call good luck and fate? Your luck will end.

Luck can also be a belief in an organization of fortunate and unfortunate events. Luck is a form of superstitionwhich is interpreted differently by different individuals. Carl Jung coined the term synchronicity, which he described as "a meaningful coincidence".

Belief in the extent of Divine Providence varies; most acknowledge providence as at least a partial, if not complete influence on luck. Christianity, in its early development, accommodated many traditional practices which at different times, accepted omens and practiced forms of ritual sacrifice in order to divine the will of their supreme being or to influence divine favoritism. The concepts of "Divine Grace" or "Blessing" as they are described by believers closely resemble what is referred to as "luck" by others.

As a self-fulfilling prophecy

Some evidence supports the idea that belief in luck acts like a placebo, producing positive thinking and improving people's responses to events.

In personality psychology, people reliably differ from each other depending on four key aspects: beliefs in luck, rejection of luck, being lucky, and being unlucky. People who believe in good luck are more optimistic, more satisfied with their lives, and have better moods. People who believe they are personally unlucky experience more anxiety, and less likely to take advantage of unexpected opportunities.[10]One 2010 study found that golfers who were told they were using a "lucky ball" performed better than those who were not.

Some people intentionally put themselves in situations that increase the chances of a serendipitous encounter, such as socializing with people who work in different fields.
