In order to transform our minds we need to train our minds in the practice of concentration so we can deepen our understanding or realisations of the teachings of the Buddha. In this set of teachings Geshe Tashi advises us how to develop the quality of shamatha or calm abiding.
"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
