She may present herself in this really connect and mystical way, but she is very human. Her artisrtic practice centers in performance, which dives and explores ritualistic aspects of living, so I undertand why she come of as a witch type. I reccomend you watching the documentary she did in Brazil, The Space In Between, in which she explores a variety of local spiritual practices, including João de Deus/John of God, who is now a convicted sex offender and criminal, and can be actually compared to Rasputin as he held such local political and economical power (i reccomend the maintenance phase episode on him, they do a good job debunking his techniques - https://open.spotify.com/episode/3t1hjrqB7cXs9HTWxPqVgU?si=712bb5f30ce54bbf). Though when she recorded the documentary he was still very respcted and the accusations hadn't come out yet, there was already many people exposing him as a con artist. You can see that her enchantment with such things come from the same naivity and somewhat fetishistic views many Europeans, and North Americans have with South American, African and Asian countries and their cultures.
For me, this makes it very clear that she is just like anyone who is a little interested in spirituality, someone who is open to exploration but can also be swayed by her biases in this process.
Anyway, I also really like most of her work, but I find it important to dismistify her artistic persona, which is now a clear part of a succesufull brand.
