Guilherme Barcellos Carlos de Souza

Family constellation facilitator, trainer and shamanic practitioner, Florianópolis, Brazil

Guilherme Barcellos Carlos de Souza, also known as Gui Tantan, is a therapist in Florianópolis, Brazil, who trains others to facilitate shamanic family constellations.[1][2] He holds a Master of Arts in Spiritual Psychology from the University of Santa Monica in California, and is certified in family and organizational constellation through Hellinger Sciencia, the school of Bert Hellinger, who created the method.[2][3] He teaches constellation work to psychotherapists in Brazil, South Africa and Mexico.[2][3]

With his partner Iana Barcellos he runs Caminhantes do Amor, a Florianópolis practice offering systemic shamanism, psychotherapy and training.[4][5] His work joins constellation to ritual from African and American shamanic lines, among them Kambô, temazcal, vision quest and Bhula, the Zulu divination he learned in KwaZulu-Natal.[6][13] He also runs constellations with horses.[12]

He holds a postgraduate qualification in medicinal cannabis, taught in part by the Brazilian neuroscientist Sidarta Ribeiro, and has practised some of his therapeutic methods since 1996.[3]

Family and organizational constellation

Guilherme is a "Constelador Familiar e Organizacional (Hellinger Sciencia®)" and a "Formador de Consteladores Familiares Xamânicos", a trainer of shamanic family constellation facilitators.[2][8]

Across three articles in 2018 and 2019 he set out the "Three Orders of Love" at the heart of Hellinger's method.[9][10][11] Inclusion: everyone who belongs to a system has an equal right to belong. Hierarchy: whoever came into the system first takes precedence. Balance: what is given must be received in comparable measure.[9][10][11] When one of these orders is broken, it shows up as a symptom in a family member, and constellation work sets out to restore the balance.[9]

He also brings constellations into businesses, a practice that runs back to Insa Sparrer and Matthias Varga's work from 1994.[8] In 2016 he ran a session in Cape Town, South Africa, that used horses to help a training programme choose new leadership. The founders of Guia da Alma, the platform he writes for, used one of his constellation sessions in the company's early days.[8]

Caminhantes do Amor and shamanic lineage

Guilherme and his partner Iana Barcellos run Caminhantes do Amor together.[5][2] The practice is based in Florianópolis and offers systemic shamanism, psychotherapy and training.[4]

It unites family constellation with ritual, shamanic travel work and what he calls teacher plants.[2] The ceremonies he draws on come from African and American shamanic lines. They include Kambô, the secretion of an Amazonian frog introduced into the bloodstream; temazcal, the Indigenous American sweat lodge; vision quest, a multi-day fast in isolation; drumming to recover lost parts of the soul or to meet power animals; and cord-cutting and past-life wound work, which he learned from the shaman Foster Perry and which he traces to ancient Egypt.[6]

He has written in support of the legal and medical recognition in Brazil of plants including ayahuasca, peyote, psilocybin and cannabis, and of their use in shamanic and therapeutic settings.[7] He offers psychedelic-assisted psychotherapy and cannabis therapy as booked sessions.[3]

Constellations with horses

Guilherme is a "terapeuta holístico, mestre em psicologia espiritual, constelador familiar xamânico e instrutor de Constelação no Brasil, África do Sul e México".[12] One of his methods brings horses into the constellation.

He has written a detailed account of one such session at Chácara Santa Cruz on the island of Florianópolis, for a couple deciding whether to separate.[12] Horses stand in as representatives for family members or dynamics, and their unscripted movements are read as information about what lies underneath. He works the method in three ways, which he calls behavioural, intrapsychic and systemic.[12]

He works the same way with organizations. In the 2016 Cape Town session, horses helped a training group settle on new local leadership for a course.[8]

Bhula, the Zulu oracle

Bhula, also called Búzios, is a Zulu reading of bones, shells, stones and other objects, a system Guilherme compares to Tarot, runes or the I Ching.[13] He learned it from his teacher Umkhululeko Gogo Nomzimane in KwaZulu-Natal, South Africa, and signs several of his articles as Sangoma, the Zulu word for a traditional healer and diviner.[13][9][10][11]

Bert Hellinger spent more than sixteen years as a Catholic priest and teacher among Zulu communities in South Africa before developing family constellation in Germany, and the Three Orders of Love draw on the Zulu concept of Ubuntu.[13] In his sessions a Zulu bone reading helps clients decide what to work on.[3]

Cannabis, psychedelics and other therapies

Guilherme holds a postgraduate qualification in medicinal cannabis, with teaching from the neuroscientist Sidarta Ribeiro.[3] His cannabis therapy protocol raises oil doses gradually under his supervision, and he regards cannabis as safer than alcohol or pharmaceutical drugs.[3]

He also offers Reiki, an approach informed by Internal Family Systems, and a psychedelic-assisted psychotherapy protocol of preparation, substance and integration sessions, which can build on earlier work in psychoanalysis, Spiritual Psychology or family constellation.[3] He has practised some of these methods since 1996.[3]
