According to the Vedic Norms, the location of the kitchen has been defined keeping in mind the solar energies and Indian climatological aspects. Northwest is the second option for the kitchen which has the vibration of Air element. The reason logically is to attain the solar positive energies while cooking as positive thoughts during the preparation is absorbed by the food and it. It lessens the impact of the kitchen facing either south or west. The Kitchen Plate reverses the direction causing dosh to North or east for positive energies to let in.
Kitchen plate would be installed on the west or south wall above the burner at the human height.
The Kitchen plate helps in preventing the negative energies to come in and converts these negative energies into positive and hence allows the user to work easily and prevents dosh.
