Namaste Sir, I created a chart Yantra with a yellow sketch pen. highlighted the 4th house of the chart yantra and stuck it on the north side of the house. There was fight between my mother and my grandmother frequently and mostly on purnima. My mother acts psychotic at times. I dont have her birth details but based on my d4 her moon, Jupiter and mars are badly afflicted. Surprisingly YANTRA WORKED! I made it under good mahurat while chanting GURUVE namaha. Sir, could you please guide how long its safe to keep the yantra and when to submerge in water. If so.
