"Mind Training" is nothing otherworldly but merely exercises to modify/change one's attitudes and perspectives. The reason for such changes can be just to maintain equanimity when going through the everyday vicissitudes of life both good and bad.
A highly practical discipline and training which is especially needed today given all that is currently going on in the world.
