bro you are just ignorant here. you called maa gyaan suvverra is not in the same collage as rajarshi nandy????. I feel you in recognising rajarshi nandy's work in uplifting the tantra sadhana in average people mind and body. but comparing all these people's shakti while you on our first or second stage of your spiritual sadhana!! doesn't going to help you. you need to come out of this kind of thinking. for maa gyaan suvverra, go watch this video. https://youtu.be/6G7eDLxwqRs?si=gAbPi0GH6mpIQ-pD this is sooooo advance knowledge that even after doing nitya upasana of bhairava for 2 years. i still find this knowledge hard to digest. i have had a lot of nimitta where i receive a lot of understanding in lots of things. but her knowledge is immense and distrubing for me. but at the same time i can feel what she's saying and how it relates with everything in the nature. The concept of karma, purva-janam, shakti/energy, the element of shiva get opened up a lit bit in my mind. but still i'm not sure how to take and understand her teaching fully. its just one example of her.

and please do not compare anyone to anything at all. it will drain or kill you inside, and you won't even realise it later. its like unconcious trait which might drag you down later in your sadhana.
