I cut grooves on three sides of a toilet, inserted steel strips and kept artificial green plants inside, but got no result. Why?
Metal is a good conductor, so it carries and spreads energy instead of blocking it, and blocking works only when it covers all sides. Metal should not be put into the ground for this. Use a bad conductor, just as the plastic cover on an electric wire stops the current from reaching you. Plastic pyramids and random items sold in the name of vastu do not help.
If doors are already open on wrong padas, how are they treated in interior vastu?
Vedic vastu says the defects of a wrongly placed door can be removed through the decoration of the door itself: auspicious symbols, yantras, paintings and artworks made on the door, door power at the threshold, and a bandhanwar (toran) hung on it. This class therefore treats wrong doors with symbols, torans, bandhanwars and colours rather than structural changes.
If the North is completely closed, can plants be kept overhead or on the terrace?
Some part of the house will have an open North; plant there. Small pots can also be kept up in the North; there is no problem.
If there is a cut at E2 (Parjanya), can it be corrected with a symbol?
Parjanya, the devta that brings rain, production and everything else, works like a lens that captures the sun's rays; when it is balanced, it captures the cosmic energy fully. To balance a cut there, the one remedy given is the plant taught for Parjanya: a haldi or daru haldi plant in a pot.
In a flat the structure cannot be changed. What can be done?
That is exactly what interior vastu is for: balance the element with its shapes, symbols, artifacts, idols, showpieces and materials to nullify the defect. For example, silver represents the Moon, so a silver artifact or a moon figure can be placed there. Like a doctor's supplement for a vitamin deficiency, the missing element is supplied; Ayurveda, allopathy, jyotish and vastu all run on the elements.
My Mercury is debilitated in the 4th house with an exalted Venus; will plants in the North cause a problem?
No problem at all. Flowering plants represent Mercury, so keeping them in the North strengthens a weak Mercury. Keep up good work such as paying for poor children's education and sharing knowledge.
