This is a very useful and beneficial Yantra. It combats all the bad influences & ill-effects of Vaastu faults existing in one's home or office. Mostly, there are certain inherent faults about direction, location, situation of a building, situation of rooms etc, which may not be easily curable or rectifiable. The Vaastu Yantra not only helps to cure all inherent Vaastu faults and remove their ill-effects, but also generates the positive & benefic effects of Vaastu. This Yantra should be either be buried under the ground before or after construction, with due rituals, or installed at the 'Pooja' room, and worshipped.
Beej Mantra for this Yantra :-
"Om Aakarshay Mahadevi Ram mam Priyam Hey Tripure
Devdeveshi Tubhyam Dasyami Yanchitam"
