For centuries Christian and Buddhist monks practiced mindful awareness skills to be present in their relationship with God. These monks became experts in watching their human mind. Over the past 40 years science has become interested in their findings. Studies show that the practice of mindfulness is effective in reducing depression and anxiety symptoms. Additionally, spirituality is a protective factor for substance abuse and suicide.
