Each of the 32 devtas of the outer band has its own tree. Planting that tree at the devta's place, on the pishach bhoomi or along the boundary wall, makes the lokpal stable; it connects with cosmic energy and feeds energy to the pishach, manushya, dev and brahm bhoomi.
Pishach bhoomi and boundary wall, at each devta's place
Into four: the outer pishach bhoomi (pishach veethi), then the manushya bhoomi, the dev bhoomi and, at the centre, the brahm bhoomi. This is not the division into padas; it is the first division of any land, plot or flat.
Zone the complete plot. Almost the whole plot is in use and even the small strips are being used, so the full plot is taken for zoning and for the degree.
Tilt means tedha or tirchha: how far the true North is turned from where it is assumed to be. People who do not know vastu simply say their house is North facing, but a careful degree reading may show that it is turned, say, 5 degrees.
Compare it with the nearest cardinal direction. South is at 180, so 216 minus 180 gives 36 degrees: the South has moved 36 degrees to the left. Do not measure it from West (270), which would give 54 degrees and shift the whole zoning.
To the left. The drawn line reads 2.4 and North is at 0, so North lies 2.4 degrees back toward the left.
Google Earth with the ruler works only on a laptop or PC. On a phone you can use a photo editing app instead: take the chakra image in PNG form, ask the client for a photo of the map and overlay the chakra on it, which needs some photo editing skill.
Draw a straight line upward from the centre. With a Shakti chakra, which has degrees printed on it, place it so that 2 falls on that line; North then lies two marks behind automatically. With a plain protractor, place it at the centre, count 2 degrees back and mark that line as North.
Not necessarily. A magnetic compass shows North directly, so its reading can be stated straight away, for example North 30 degrees toward East. Google Earth and the mobile app only show the heading of the line you draw, and North has to be worked out from it; a heading of 2.39 means North lies 2.39 degrees to the left.
Open the location in Google Earth with North set at the top and compare. If the plan looks identical, it is drawn at zero degrees and is zoned without rotating the chakra; about 90 percent of such tilted maps are drawn that way. If in doubt, rotate the map until one straight side is straight and take the tilt from that side.
Ask the engineer who draws the basic plan to show the surrounding roads, straighten the road in your map and take the road's degree. You can also use any parallel neighbouring building, since parallel buildings always read the same, ask the engineer which line the house will follow, or visit the spot.
If the plan came tilted and was not drawn to zero degrees, rotate the paper until one straight side of the plan is exactly straight, checking it against a straight line. Do the full zoning in that position, and only then turn the page back as it was.
A pad is one of the equal sections into which a plot is divided. For 81 pad vastu a house, for example 90 by 90 ft, is divided into 9 by 9 equal sections and each section is one pad; the larger grids, such as the 1000 pad grid, divide the plot into many more equal sections. Some areas such as the Brahmasthan cover several padas together even if the drawing does not show their inner divisions.
