From Harris Park. Meditation on the joyful, soothing breath. Dhamma talk on the three characteristics in historical context and their practical relationship to liberation: anicca (impermanence/not-regularity-ness), dukkha (suffering), anatta (non-self). Why are all conditions suffering but all dhammas non-self? The three characteristics as doors to dhammas of the great teachers.
Using the body's sensitivity we can notice what stabilizes and gladdens the citta, that moment the Buddha touches our heart. How can our practice continue this? Ajahn recommends cultivating sampajañña - fully and directly knowing what’s happening - and describes its four qualities.
