Mindell has also published books dealing with large group conflict resolution and leadership, notably "The Leader as Martial Artist: An Introduction to Deep Democracy" (1992) and "Sitting in the fire: Large Group Transformation Using Conflict and Diversity" (1995). Mindell advances a concept and principle he calls ‘deep democracy' and the approach has been compared to the work of Danaan Parry. Mindell's group conflict work has been reported within a business setting and within large community forums working with racism and other social tensions. Mindell's concept of 'rank,' published in his book "Sitting in the Fire", has been used to support greater gender awareness in mediation training.
