Taking the Buddha at his Word by Thanissaro Bhikkhu

"A Sangha is a community of resistance, resisting the speed, violence and unwholesome ways of living that are prevalent in our society. Mindfulness is to protect ourselves and others. A good Sangha will lead us in the direction of harmony and awareness. The substance of the practice is most important. The forms can be adapted."
~ Thich Nhat Hahn
