How to get rid of Yakshinis and negative energies.
My guru gave me a general Shakti mantra to chant along with telling me to offer meat to Kateriamman. I was doing vamachara worship as I was told. I was doing japa and worship for a few months and I did a yajna for Kateriamman, which was devotional, looking bad it was missing a few steps but i did it to invoke Kateriamman into my Trishul. I've been giving her meat and all, but I didn't receive any kavacham or purification mantra from my guru, thus all I do is I purify my room with incense smoke, with water combined with gayatru mantra at the entrance of my room, in my whole room and then altar, I also purify the food with water combined with mantras, such as Nama mantras, and her main mantra and end with a mantra of her naivedyam samarpayami. But I've experienced possessions, and when I did cleansings with lemon once, it actually worked. But ever since I started this path, my mother has been having so much bad luck, her foot and legs have been hurting so much, she has gotten minor fevers, troubles with her work assignments, and overall lack of motivation, sleeping problems, waking at random hours, and all but I've tried to help her with cleansings Also, a during this period, a picture frame of our whole family fell and broke at the edge, my sister's Venkateshswara poster fell by itself, my mother's beloved pendent fell from inside her drawer onto the ground. I've stopped doing meat offerings after my parents found out I was and told me to do visarjan of my Kateriamman trishul and so I did. But that same night, my mother dreamt of random dogs coming into our home and pooping everywhere and rolling in that poop. And also she woke up in the middle of the night and dreamt of robbers entering her room in the dark whilst she was awake. I also chatted with a siddha, who told me that I had invited Yakshinis and negative entities into my home and that my mother was suffering Mostly, but that due to my giving others advice on tantra(I gave some people generic Sadhanas), I had taken negativity upon myself, and also that the visarjan did no help since the energy is still here. What should I do?
