Very few men can execute their wives as Bhairavi. Even though Kamasutra speaks about Dharma and the execution with the consort. A lot fail to understand the basic of Kamasutra which actually revolves around Dharma artha kama and then moksha. But many feel “kamasutra” is a book of kriyas and sex- its book of sexual kriyas to conduct yourself in an absolute dharmic way.
In Bhairavi sadhna you can’t lust your bhairavi. You overcome it through your kriyas.Eventually the Bhairavi turns into Matri swaroopa as a source of energy. Here your karmas get attached to her for 3 cycles of Bhairavi Chakra which is equivalenr to 3 births together. Its impossible to come out of it, before completing the cycle.
If a person tries another Bhairavi(female) it will be a temporary transmutation. In yoni tantra, Bhairavi is said to be the “sarvsrastha” Kamakhya Yoni emiting different radiations and frequencies of energies once her energies are invoked. Other’s energies unless invoked(Avaran pujan of Devi) wouldn’t give results.
