In this videoconference talk from 29 March 2019, Ajahn Anan discusses concentration and communal bonding.

An excerpt: "Sometimes people may ask, in this life will I be able to have concentration? If one has effort and diligence, then one will be able to gain concentration. If one is determined to make their hearts have peace and inner happiness, then they must keep trying and putting forth effort. If concentration arises then the mind is cool. It’s like planting a tree and the tree slowly grows bigger."
