stambhaṃ vā bhavanaṃ vāpi dvāraṃ vāsagṛhaṃ tathā.
diṅmūḍhe kulanāśaḥ syānna ca saṃvarddhayet gṛham .. 256.28

The ceremony "Prâkudakravan' is to be performed with regard to the pillar, but one should be careful not to make error as to direction, on the top of the pillar is to be placed a young twig with fruits attached to it If there are confusions and errors as to the directions with reference to pillar houses rooms or doors or dwelling room, it means the extinction of the family.—27-28

Such a flaw should be carefully avoided in fixing up the pillars making the doorways and also in the dwelling places for if it is allowed to remain in them, it means the destruction of the household The house should not be extended in one direction only If extension is to be made, it should be made uniformly and symmetrically in all directions If it is to be extended towards the east it creates enmity.—28-29
