Vaastu Shastra is incomplete without astrology. Vaastu for a particular place has to be done in connection with the owners or tenants birth, date and time, planetary position including the date on which one signs the agreements to buy or rent the property.
According to the rule of thumb of vaastu, North and East are considered to be auspicious directions and South and West are considered inauspicious and negative directions. This means that people who have their house and office facing North and East should always prosper and lead a peaceful life and people who have their house and office facing South and West should always suffer and face failure in life. However, in reality, this does not happen. This is where vaastu and astrology are integrated. It is the birth planetary chart of an individual which decide the right direction, fortune and not the thumb rule of thumb of vaastu.
Each direction has it’s own vibration and it is the planetary position of the individual which decides their favourable direction. For example, there is this big fear among people that South is a negative direction. This is a big misconception because it is mentioned in our shastras that a person who has a strong Saturn or Mars in his horoscope would always be successful if he has a South facing house or office.
