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.
Tulsi absorbs the rays of the sun and, because of its mercury content, spreads that energy through the whole house, which is why tulsi pots are kept in the zones from North-East to East.
Flowering plants in the North strengthen Mercury and make business shine; factories with flowering plants in the North are seen to run well.
It depends on the house. When a lot of land around the building lies unused, take only the constructed area and zone it separately. For a normal plot of about 2000 sq ft with just a parking and a small front garden, take the whole plot, and mark the devtas and marma on the whole as well. Small houses of 1200 to 2100 sq ft are taken whole, parking included.
Take the centre of the whole plot and map the devtas on it; all the open land around the house, even outside the building, becomes space for the devtas. This is why big houses abroad, as in America, are so balanced: about 4,000 sq ft is built on about 40,000 sq ft of land, so the 32 outer devtas get a huge, open pishach bhoomi and the manushya and dev bhoomi get cross ventilation from all sides. Just as a person given two acres of land enjoys the space, the devtas are pleased by big open land.
Yes, it is not good; industries whose corners were fully covered have suffered losses. The rule concerns the corners of the whole land at the boundary wall: covering inside an industry or along a side is acceptable, but not a corner (vidisha). A small 3 to 4 ft landscaped bed in a corner is fine; the problem is when the whole zone, for example the entire South-East area, is covered.
Yes, a garden can be made in the East; even a bedroom can be made there for a person whose Sun is exalted.
Only one tall tree is allowed in the North-East, the coconut, which draws cosmic energy from above and passes it down. No other tall tree should stand there. If one already exists and cannot be cut, plant energy-capturing plants such as tulsi in the North and plant tulsi all around the tree.
Certainly. Drop the idea that there should be no greenery in the North-West or South-West; gardens and resorts everywhere have greenery on all sides. A vastu expert should never get a tree cut, because its dosh falls on him; plant auspicious trees near it instead.
No fruit-bearing tree is meant to be an indoor plant. If there is a garden, plant it there, not inside the house; otherwise fruit trees bring trouble for the children, as Varahamihira says.
Such a door is not counted as an entry; it is a prishth bhang dwar (rear door) that lets the negative energy of the house out. Energy enters with you through the door you come in by. No treatment is needed; if it bothers you, draw the energy-blocking swastik. Symbol vastu especially suits countries outside India, where demolition is not possible.
A fruiting mango tree need not be removed: build a boundary and chabutra around it and keep a tulsi plant there. A pomegranate can be moved with its roots to another place; if it cannot be moved, pour desi cow urine at its roots and place tulsi near it.
