The main door should open inward into the house, and towards the left. This allows energy to enter and flow freely. Doors that open towards the right or outwards are not considered auspicious.
Creaking sounds made by un-oiled doors kill the positive energy that is about to enter or already exists in the building. Make sure that you lubricate the hinges of all doors (main doors, room doors, cupboard doors, etc.) at regular intervals to put an end to these sounds. This applies to creaking windows as well.
Placing a lit diya (earthenware oil lamp) outside the main door at sunset is a good custom. It helps ward off any negative energies, and also works as a security measure against evil forces.
The door should be decorated by auspicious symbols such as an image of the kalash, with coconut on it, Goddess Lakshmi’s charan (feet) pointing towards the house, or a Swastika with ”Riddhi Siddhi” and ”Shubh Laabh” written on either side of the symbol — the Swastika represents Lord Ganesha, while Riddhi and Siddhi are his two wives, and Shubh and Laabh are his two sons.
The main door should also be the most attractive door in the building. It is believed that Goddess Lakshmi enters houses whose doors are beautifully maintained. The same stands true of positive energy as well. Hence, it is important that the main door is kept clean at all times, and is not worn out.
The main door should not only be bigger than all the other doors in the house, its dimensions should also be as defined by Vaastu. ideally, its length and breadth ratio should be 1:2. In some buildings, due to the low height of the ceiling, the height of the door is low; while in others, due to shortage of space, the width of the door is less. This creates problems in energy flows related to opportunities and wealth.
Central space is better left open or used for rituals. Kerala’s /Rajasthan’s traditional four sided house with a central courtyard and verandahs all around, is ‘model’ of Vaastu design.
