Selection of plot according to slope: The Plot or Site of construction according to Vaastu Shastra can be divided in to two the North East half of the plot and the South West half. The North East half of the plot is called the Solar half and the South West half is called the Lunar half.
Vaastu Shastra suggests that the Solar half should be lower and the Lunar half should be higher. This ensures the ideal flow of light, solar energy & polar energy. This type of plot brings joy and happiness, good children and all the success in life to the occupants of the building erected on it.
One should avoid plots humped at the center and sloping on all sides. Same with the plots that are depressed at the center.
The north east side of the land should be the lowest side. The land should either slope down towards the North or East, but never towards the West or South..
