The recent murder of Elana Fric-Shamji in Vaughan, Ontario, Canada, to my mind, demonstrates that we still live in a culture that is sexist (inequality of gender), misogynist (a person who dislikes, despises, or is strongly prejudiced against women), and promotes violence, in all its forms, against women.
There are two ways of being in the world. One is called the "doing mode" and the other is called the "being mode". When we operate in the "being mode", we are usually happier than when in the doing mode, for obvious reasons. If you are in the being mode, there is less of a tendency for you to be excessively angry. Mindfulness, therefore, is an anger management strategy because it is a source of happiness.
