Interior work done without vastu can ruin a business even when all directions are correct: anti-element materials and colours, the most harmful (marak) colour of the owner's kundli, or a main table placed with zero aay all cause losses. Symbols, swastiks and corrected colours can restore it.

Underground, copper is the best metal because copper and land both belong to Mars; it ionises the land and generates a current. Planet-wise metals are used when orienting to cosmic energy above ground, so a silver kalash goes above ground in the North-East.
Underground: shilanyas pits (ishaan, nairitya, vayavya); above ground: North-East
