I'd like to offer an insight. I'm learning to recognize & synthesize the different aspects of personality & also oneness with others. I'm finding that when I forget to meditate or at least remind myself during the day I start getting moody & more irritable. I feel it's important to connect with both left & right sides of the brain & for me, since I'm predominantly a yang/rational/left brainer -lol- it's valuable to connect with my recessive yin/spiritual/right brain side, as well. That's where meditation or spirituality comes into it. I suppose that's even why I'm in this forum.
