Did this one early in the morning on my seiza bench. While kneeling on the seiza bench it is harder to do the belly breathing , the abdomen is a bit tight in that position. Did the long MCO , 26 minutes. Sensations were the same as yesterday , concentration was good. There was some slight discomfort at times at the base of the spine. The energy ball was large and bright today. When the ball goes up the spine , I imagine it going through the interior of the spine and see the light shining through the spaces betwen the vertebrae as it goes up. Right now there is a sensation of subtle heat/warmth in the spine at the height of the kidneys , higher than the heat yesterday evening.
