there is something for everybody

What is Aghora Tantra? Robert Svoboda wrote about his teacher, Vimalananda, in several books, and he was an Aghora Tantric, yogis known to eat human flesh, conjure magical powers and perform "crazy wisdom." Here is a short explanation Shrii Shrii Anandamurtijii about the three paths of Tantra, including Aghora or the Left-hand path.

"The terrifying form of Shiva is called Aghoranatha. Aghoriis or those that follow the path of Aghora are generally Vámácárii Tantrics [Tantrics of the left-hand path]. None of them are Madhyamácárii [Tantrics of the middle path] or Dakśińácárii [Tantrics of the right-hand path]. It is said that they do not discriminate between edible and non-edible food. For this reason many people are afraid of them and try to avoid them. It would not be correct to say that all Vámácárii Tantrics are Avidyá Tantrics. Among them one will find both Vidyá Tantrics and Avidyá Tantrics. Towards the end of the Buddhist era, this Aghora path could be found alongside the Vajrayána and Kálacakrayána. Some people believe that when the Vajrayána and Kálacakrayána fell under the influence of Hinduism, the Aghora path certainly also fell under that same influence, but this is not so. Though the Aghora path does not follow the Buddhist doctrine, neither are its followers, followers of the Vedas. Rather they are clearly opposed to the Vedas. In Hindi and throughout north India, the followers of Aghora are called aoghaŕ." (written by Rameshjii)
