I am practicing Pranayama Yoga meditation and Zen Meditation ( I started about 2 weeks ago). I was told that thoughts come but you must focus on your breathing, which I do. But when I meditate I have NO thoughts coming and bother me. Is it normal? My Meditation is fine but Am I normal? All the people who practice meditation told me that thoughts come over and one should allow them to flow but concentrate on the breathing only. How come that I have no thoughts during meditation?
