I attended psychic energy class on 20.1.19 in chennai. In the class we measured energy levels of our house with pendulum as taught by our guruji. My pendulum showed positive on all the rooms except near the entrance. After the class, I came home and measured once again. The result was same. I was worried if there would be any vaastu defect. Today I noticed a letter cum key holder on the wall. I removed all the keys and checked again. To my surprise it showed positive. I carefully checked each and every key and finally found all the keychains showed negative. I replaced them with new ones. Now the pendulum shows positive on all sides. Thanks to our guruji for giving such a wonderful tool and alpha.
