It is clear from the word “Vastu Shastra” that the science of Vastu is Vastu Shastra. Shastra means science, that’s right, it is Vaastu Shastra that our ancestors wrote after scientifically studying the geographical conditions ,changes in weather, temperature in each season, the human body living in those conditions. Why would there be a need to write vastushastra? First of all, when humans were born, humans also lived on trees, in the forest like all other animals. Gradually, with the strength of their intelligence, they began to study deeply on how to live in harmony with nature. Now see earlier man used tree leaves as clothes, then after that many materials were used as clothes. Finally he invented cotton then they made silk cloth.                  The same happened in the science of food, earlier man lived by eating fruits,roots, hunting animals and roasting them, then he discovered many spices, then the things that were eaten only by roasting started to be eaten by cooking, frying and steaming. This later transformed into culinary science. So many such scriptures were written by human beings for their own evolution, for the convenience of  time and such scriptures that do not harm the body. While writing any science, the science is created by considering the geographical conditions of the region where the human lives, the changes in the climate, the temperature in each season, the human body living in that situation and the availability of the things that are used.                                                        Our earth is made up of five elements (panchamahabhuta). So what is this five elements? Creation was created from the five elements which are water, air, fire, space and earth. These elements are also included in our body. Whether we were taught in school that our body, food is made up of these five elements. Then, using these five elements, man created his Vastu (house). That’s why water, air, fire, space and land were used in earlier houses, that’s why in earlier construction we used wood, soil, stone, balance of air, right direction of fire, right direction of water, all these things were used properly and in the right direction. This material was easily available to us, this material contains the same five elements that are present in our body. So will a house built from such materials be harmful or beneficial?                                                              Now we will consider the atmosphere and season? Different geographical conditions can be seen in different parts of our Maharashtra. E.g. If we go to the Konkan belt, there is more rainfall, the heat is less because of the hilly area, it is also very cold due to the constant drainage of water, then considering what kind of house should be built in such a situation, the sloping roofs, ground level houses, covered with mud, or chira. Houses were built with purple stones and dung soil. Due to which the people who see these three seasons easily face the temperature of that season, face the situation and make their life pleasant.                                                                 If we do the same study on areas like Karad, Satara, Kolhapur, Sangli, Solapur, Ahmednagar, then there is a changes in the climate like the amount of rain decreases, due to flat land and lack of trees, the heat of the sun increases and the cold is harsh. Then by studying such conditions in those areas Black stones were used to build houses. Due to the low amount of rain, the roofs of the houses are not sloping. These black stones work to keep the interior of the house warm in winter and cool in summer, so the houses are built using these five elements according to the conditions.                                                   From all this, we learned that the human body gave great importance to the human body while inventing any science, because if the body is not in order, then it naturally affects the mind. That is why more attention has been given to how every family, every person can get physical, mental and financial happiness.         1.     There are two or three things to keep in mind while creating these structures. Earlier, toilets and bathrooms were not built inside the house, so why? Although the house was large in size, but there must be some scientific reason why those two things were not given a place in the interior of the house? My personal opinion is that most of the running water and sewage drainage were kept away from the residential building so as not to come in contact with the main building and disturb the balance of energy there.                                                            2.   Another thing is that during the construction of houses in the past, pillars were not used in their walls. Either a thick stone wall was built or a straight wall of mud and bricks was built. The energy imbalance in the house will be increasing due to hindrance or opposition to the energy of the incoming five elements. In the current construction, whether it is a sitting house or in a building, pillars are used in every house. Even in the olden days, tall buildings were built, palaces were built, but the use of pillars is not seen anywhere.
