desinari

Couple of years back a Kuber yantra was given to my husband by an astrologer for wealth betterment .We kept it in our temple area ,then someone said it is better to hang on the nomain enterance door inside so that the yantra faces the house. Now it is in this position .Either way overall our financial position has gone from bad to worst to negative and very hard to survive.My question is Should we even keep this yantra at home? If yes What is the best position /place to hang or keep this yantra in a North facing house and toilet in northeast position? Please advice. Reply would be highly appreciated. thanks
