The mandir or prayer room holds a very special position in a house. It is a place of devotion, hope, trust, truth, and even refuge. In view of the mandir’s immense significance, it is essential to create a space that embodies the best possible principles of vaastu.
The best direction to worship in is the northeast; the sun’s first rays fall in this corner, making it very sacred. In vaastu science, the northeast corner is known as isshan (corner for ishwar or god). This direction is also recognized as the point from where earth’s powerful magnetic energy is generated. Therefore, this is an ideal location for a mandir. However, if your mandir is not situated in the northeast, make sure that you face this direction while praying.
Wood and marble are the best materials to use when constructing a mandir.
Make sure that the mandir is not positioned next to the toilet. One should also avoid building a mandir in the bedroom or the kitchen.
It is also not advisable to build a mandir underneath the stairs, or construct any structure over the prayer room, as you would end up symbolically stepping on it.
The idols and images of gods and goddesses should be placed on a wooden platform. The idols can be kept on marble and stone also.
If it is wood it should be pure and tree would only. Rose wood is very pure and good. Ply and laminated boards are not pure wood.
Make sure that the size of the idols is not more than the size of the thumb of the owner of house. The idols which are bigger than the thumb are supposed to be in society mandir/ common mandir. If the idols are larger than the thumb size, pran prathishta has to be made in the idols. It is a ceremony while keeping establishing he idols it is meant that the power has been put in the idol. After that the idol is to taken care as a human being because it is considered that the idol has prana energy(life energy) in it. This is also mentioned in the “purans”
Avoid placing too many pictures or symbols – shiv lingams, conches, etc. – of a single god. It is a point of respect, faith and value we give to our god. These should not be kept in our living rooms, drawing rooms and other places. These are our personal places, we eat and relax there. God pictures and idols kept here and there gives a sense of modern spirituality and faith. But God is all mighty we keep them any where, or hang them on wall, just to fulfill the fashion in the society. Conch is considered as a very scared identity in hindu culture, and in lots of places it is displayed as a showpiece.
In the scriptures a specific number is mentioned for each and every diety. The place and the directions are also mentioned. The nature and charteristics of ritual also varies a liitle bit. It is a rule we can not change. There are 33 corers devtas in the hindu cluture. It will be difficult to mention all of them.
Make it a point to light a diya (earthenware oil lamp) or burn incense before the gods in your mandir every evening.
Never place pictures of deceased people or your guru in the mandir. The deceased people and gurus are human being and in comparison to the god the position/grade is lower. So these should not be kept in same level and same place with the god. The wall can be changed.
Placing pictures, idols and tiles of Lord Ganesha on gates and at the front of a house is not advisable. This is because Goddess Lakshmi’s sister Daridrata, whose name also means poverty, is featured on Lord Ganesha’s back. So, when you place the god with his back to the house, you are, in essence, inviting poverty into your house.
