I have appreciated a handful of good mindfulness teachers in the last decade and a half.  My favorite teachers are not only soulful people and good at explaining the dharma or practice of mindfulness, but also have their feet firmly planted in what's actually going on in our country and show their own sense of bodhichitta by striving for ending all beings ' suffering.  Among them, Tara Brach. Here's a page of resources that Tara Brach has shared with us and I pass on to you.

I agree with Tara that now is the time for each and every one of us to stepforward and take part in attending to this core wound of our society, and to prioritize clearly seeing the conditioning of racism and White supremacy that keeps us locked up in delusions.  Our choice to learn about racist ideology and institutions and to choose right action can undo our own racism and the historical and institutional racism that is a life-taking and life-limiting force for Black, Brown and Indigenous people in The U.S. and in so many places in our world. We owe it to those who have and continue to suffer. We owe it to ourselves too, to liberate all those who are oppressed in one way or another.
