The book Spiritual Gaming explores a method using video games like Diablo II and Team Fortress 2, as well as board games and other activities, to teach spiritual lessons and improve self-awareness.

The author details his decades-long experiments, emphasizing the importance of teamwork, overcoming challenges, and developing skills like attention and discipline. He uses game mechanics as metaphors for life experiences, particularly the importance of staying focused on a common goal ("the Pack of Green") and avoiding distractions. The author also discusses the importance of self-observation and overcoming ingrained habits.

Finally, he connects the approach to spiritual practices like meditation and art.
