Lovely and calming, Jason offers stories, teachings, and practical methods to apply the practice to one's daily life. I'm in NYC and have the chance to practice some of the teachings all day long, particularly attempting to be mindful that the Buddha is in everyone – cab drivers, subway riders, store clerks, neighbors, homeless schizophrenic men standing on corners yelling threateningly at passersby – it is a tremendously helpful outlook.
Also appreciate that he doesn't focus on minutae of his daily life, as other podcasters occassionaly do ad nauseam. When Jason brings in his own experience, it is relevant and fits in logically with the topic. I heard his kids in the background in one just now and I really liked that, it added humanity.
I haven't heard Karen, yet, but I do look forward to that.
