Your thoughts about anything program your brain computer. Your body functions as a feedback mechanism that gives you feelings. You then say you feel whatever range of emotions you are feeling. The final computation may be to feel depressed, mad, sad, happy, euphoric, a migraine, or an aching back, etc. I purposely combined emotional states and physical conditions in the last sentence because that is how your brain functions.
Emotional states become physical symptoms.
Beliefs become so strong by reinforcement that they seem automatic to you when you simply react with emotion, but the thought must come first to feel anything. Where you get into difficulty with feelings, and aren't sure why, is when you program a belief at a subconscious level and you don't know it is there. Knowing what lessons your child came into this life to learn can be a wonderful tool for more effective parenting. You relate to your child in a more harmonious way and help encourage growth in specific areas because of you insight. Numerology can do just that.
