The doorways should never be blocked with anything The exits and entries should not be hindered by anything These being blocked by a thoroughfare, tree, corner of another house are inauspicious By its being blocked up by a lane means the annihilation of the family, by being blocked up by raised earth it brings jealousy, by being blocked up by moist soil or mud, it brings misery, by being blocked up by a well it gives epilepsy, by being blocked up by a waterfall, it brings in some evil, by being blocked up by some nails it brings in danger from fire, by its being blocked by any Deva there is danger of destruction If there is the corner of another house in front of it, it means the death of the master The doorway being blocked by a filthy drain or other impurities causes sterility to women If there be any obstruction in the shape of pillar it indicates difficulties to the wife, and if it be obstructed by the house of a lower caste, it indicates the fear from weapons No obstruction is recognised at a distance greater than twice the height of the house—10 14
