Jeff: For part one, we continue exploring concentration, this time with a master of concentration – my wife, Sarah Barmak! Every morning she makes me look bad by dropping into bliss-saturated samadhi stillness while I roll around on the floor doing my special “meditation” body exercises. How did she get so good? She followed Culadasa’s excellent  Mind Illuminated  protocol, that’s how. Join us for a trip into the depths.
