I have explained about your doubt in the upcoming video .. you need to watch next 15 videos to understand it .. in some cases few questions are very broad can not be addressed in single comment reply.. you can call it *no reply*, revenge or whatever .. I leave it up to your intelligence … I have told you to wait for the next 10 days but you keep bugging me on the same .. if I am not helpful to you learn from different sources dear what's the point in trying to blame me?
