How far can positive thinking take you??

Its been a long time ... and I've also grown up a little bit in this month :) . Whatever comes out my "philo bag" (Teena's coined word), is now more justified. I've been planning to write loads of things while I am at home during the weekend, but since I still believe that internet can stay away from me for at least 2 days of the week (Its better to be called as a citizen than a netizen). When I am at office, I just cant spare time to write and the miraculous thoughts just wane away. But I just pulled myself, shunned the laziness after working out in the gym, and started writing this over...after a long time indeed.

Now coming back to what I wanted to write. There has been a lot of research going around on human brain , not just in medical science but in computer science as well. The first field is more concerned with improving the brain , and the second more to imitate it!!. Nevertheless, I wont write how neurons and synapse work together here. The idea is more spiritual and abstract. Think of brain as a state machine, just like a Turing machine or your computer.
Now anything you see, listen, taste, hear and touch acts as an input to this state machine. There are other inputs to your brain , one from your subconscious (essentially gathered and mangled from the external senses listed earlier) and another from your unconscious (wanted to call it sub-sub-conscious), which is pretty much dependent on your previous incarnation (here comes the karma). Now, any input to brain from all these sources is packaged into one thing - The Thought. This thought goes over iterations in the brain to change brain's state and its own state several times over. While this process is going on, the ALU of brain i.e. cereberal, evaluates this thought and directly effects usual the body functions like digestion, blood circulation, cell creation and destruction. While the thought is being churned in celebral, you are very much conscious, because only conscious mind has the power to change the thought which is fed externally/internally to it. This is also the reason , why you get nightmares or sweet dreams, as you just cant control them. At this conscious stage, it is now very important that you take things in the most positive way and modify and shun the thoughts which could possibly take a toll on your physical health. So, remember every thought is directly connected to your physical health. The mediatation makes your brain strong enough to control your body through modifying your thoughts the way you want it. Thats also the gist of yoga and ayurveda in some sense, which believes in well being of the mind as well as body.
