NOT SOMETHING. we have to do exactly what Muslims and christians are doing. the british education system which is basically a christian education system calculatedly taught indians that there is a population growth. actually such a concept is very much false. it is being done only to reduce hindu population and hindus foolishly accepted it. but christians and muslims are very much giving birth to more than 2 every family so that there count will go up. first step is to give up this habit of family planning. every hindu has to have minimum 3 children. next part is to do exactly what muslims and christians are doing. wake up daily by 4 o clock (go to bed early first), worship for 2 hrs strictly, read Bhagavad Gita thoroughly. teach to your children. the dress in your house for all (wife, children, every one) should be strictly vedic. put tilak on your forehead, take angavastram on ur shoulder, then proceed to ur office. if any one ask - you counter question him that can you stop a muslim cap or a sikhs turban??. stop all forms of TVs, movies, newspapers etc. then this will definitely show an impact on others and your surroundings will change.
