“In one who perceives impermanence, the perception of non-self becomes firmly established,” the Buddha says in the Aṅguttara Nikāya, “and one who perceives non-self achieves the elimination of the conceit ‘I am’ and attains Nibbāna in this very life.” Here the Buddha suggests that perceiving impermanence (anicca in Pāli) supports insight into the lack of a substantial self (anattā) and can lead to liberation from dukkha. Investigating these three characteristics of existence—impermanence or inconstancy (anicca); unsatisfactoriness and discomfort (dukkha); and the lack of a substantial self (anattā)—has since the time of the Buddha been recommended as a doorway to liberation. This program will invite participants in to a deeper understanding of these three aspects of our experience of reality as well as providing some indications of how to cultivate the liberating perception of impermanence, non-self, and dukkha. We will devote one evening to each of these three characteristics, with a Dhamma talk followed by an opportunity for questions, reflection, and discussion.
