Vaastu rules say that all directions are good. However, the internal layout of the house (position of the kitchen, toilets, bath rooms, bed rooms, mandir, main door, etc.) and cuts/extensions in the shape of the house if any, decide the benefits or losses due to the energy of any direction. Thus, if the main door is in a direction which is ideal as per Vaastu rules, it will bring in good energy, but if the door is in a direction which is prohibited for an entry by Vaastu rules, it will bring in bad energy. E.g. Vaastu rules do not allow entry from the South West but insist on having the Master bed room in that direction. Thus, we see that the south west is not a good or bad direction per se; it is the best direction to have a bed room and a very bad direction to have a door. In this article we will discuss about the South East (SE) direction.
The SE direction lies between South & East and brings in energy from both these directions. Also, the related Fire element is "radiant" in nature (as compared to the Fire element related to the East which is mellower in nature). SE is related to Venus which represents the female. So the lady of the house may suffer most of the times if there are any Vaastu defects related to the SE direction.
A door in the SE direction brings in Fire i.e. anger. It creates an atmosphere of stress and tension in the family. It also brings in sickness, mostly to an elderly lady if there is one in the family. Many a times the sickness may be severe enough to make the lady bedridden, especially when a door located in the SE direction faces the South and other energies also do not support the lady.
As a remedy, if you have a door in SE, it is recommended to fix 2 stickers of the Gayatri Mantra outside the door from both the sides and place a Rog Nivaran Yantra inside the house on the wall opposite the door. Further gems therapy can also be used to protect the door. ( In fact any door which is not in a good direction can be protected from evil energy by using gems therapy.)
The Fire element of SE is also related to sex and married life. So if a toilet/bathroom or an underground water body or a cut is present in SE, it can cause hurdles in getting married or in married life or in conceiving a child. In case of any water body or a bath room in SE, one of the daughters may remain unhappy in her married life. As a remedy, fix a picture of a burning candle on the south wall of the bath room if it falls in SE. Fix Hanumaji's tile who is holding a Gada in left hand, on the wall outside the house facing under ground water tank or a well if it falls in SE.
It is observed many times that entry from North West and underground water body in South East or entry from South East and water in North West can bring in loneliness or in other words, a man or a woman may not get married or has to live without a spouse. Not getting married or not conceiving come under a category of living a lonely life. This NW and SE axis is very important axis for physical pleasure/sex life and NE and SW axis is very important axis for stability in life.
Using appropriate Gems like coral/yellow sapphire/diamond/crystals charged by proper Mantras and/or metal like copper under the floor, worshipping Hanumanji will reduce the severity of SE defects. It is better to take a guidance of a Vaastu Consultant if the defects are severe and are affecting one's life in concerned area adversely.
