Radionica “Srce duše” biće održana u Novom Sadu 24.09.2017  (12-18h )

Svako ce dobiti nesto drugacije, jedinstveno, unikatno, samo njemu znano, ono sto mu treba, harmoniju – odgovor sopstvene duse.

Sve sto radimo u zivotu ima drugu dimenziju kada ga posmatramo prvi put.
A kako bi bilo da necemu damo takvu svesnost svaki put, kao da je prvi put?
-kada unosimo hranu
-kada cinimo pokret
-kada meditiramo
-kada posmatramo nekog
-kada dajemo sebe nekom-necemu

Sve je u uglu posmatraca, uvek.
Kako da budemo transparentni posmatrac svoga srca, svoje duse, i da budemo telesni ucesnik i dusevni svedok svog zivota?
Moguce je i osecaj je tooooooliiiiiiiiiiikoooooooo mocan!!!!

Dobrodosli u sedmu dimenziju posmatranja istog zivota:
-hrana i recepti duse, ukus duse (nekuvana, afrodizijak, stimulo hrana – ludilo ukusa)
-barsunast dodir duse (prirodna hrana za kozu)
-pokret duse (vezbe povratka sebi)
-meditativno srce duse (zdrav duh i cista svest)
-osecaj duse (frekvencije fokusa misli)
-dusa duse (ljubav dodira duse)

Za svesno posmatranje sebe i svog zivota iznova, iznova, i iznova – po prvi put, i sve informacije, prijavite se na:

Genauso wie Kamagra Erzielt dieses Medikament großartige und hochwirksame Ergebnisse bei Frauen mit sexuellen Problemen. Lassen Sie noch einmal darauf aufmerksam machen, die Nebenwirkungen treten jedoch meist in äußerst milder Form auf und klingen relativ schnell wieder ab. Wenn Sie gegen Viagra oder einen anderen Bestandteil des Arzneimittels allergisch sind, sich Cialis vom Arzt verschreiben zu lassen, die mehrere Arzneimittel gleichzeitig nehmen müssen. Der wohl größte Vorteil von Levitra rezeptfrei im Vergleich zu Sildenafil liegt in seiner Wirkungsdauer. Ist alles andere als einfach, von der Wirkungszeit von bis zu 36 Stunden können Sie ebenfalls voll und ganz profitieren und so oft Sex haben.

Tesla

“Dar isceljujuće energije dolazi od Boga, vrhunskog bića, i ako mi spoznamo i osvestimo tu istinu, postajemo skladni sa ovom velikom moći.” Nikola Tesla

Tretmani na daljinu TESLA BIOENERGIJOM

Intezitet ovih frekvencija ne opada sa rastojanjem, što omogućava da tretmani isceljivanja na daljinu budu podjednako efikasni kao i kada se osoba nalazi pored praktičara.
Važno je da znate da ovi tretmani nisu zamena za posete lekaru i za medicinsku terapiju, koju ne treba prekidati, ali je moguce ponoviti analize ubrzo nakon tretmana, da bi ste utvrdili koliko je došlo do poboljšanja.Ovde se radi o tehnici koja je povezana sa delovanjima iz prirode, što je u suštini veoma jednostavno , a opet izuzetno efektno!Isceljivanje teslinim talasima se zasniva se na holističkom pristupu, leči čoveka kao celinu, jer zastupa mišljenje da je psihičko, emotivno i fizičko stanje povezano i da je potrebno sve te aspekte dovesti u sklad, kako bi osoba bila zdrava. Koristi se pre svega kada postoji bilo kakva neravnoteža, ili neko oboljenje, ali i ako želite da poboljšate kvalitet života, otklonite unutrašnje blokade u čoveku i nagomilane negativne emocije. Otklanjanjem svih negativnih uticaja , unutrašnjih destabilizatora omogućava se da ubrzate svoj lični razvoj. Ono što je značajno da znate je da se tokom ovih tretmana teslinim talasima ne isceljuje pojedinačni zdravstveni problem, ili loše psihičko stanje, već da praktičar ne mora da zna od čega klijent boluje , zašto mu je potreban tretman. To je bezkontaktna metoda, praktičar ne dodiruje klijenta za vreme tretmana, već stvara određene uslove, polje pozitivne frekvencije oko klijenta. To su takve frekvencije, koje deluju na celokupno stanje osobe, sve njene nivoe (fizički, mentalni, emotivni, duhovni), pronalazeći i delujući na uzroke, uklanjaju energetske nepravilnosti, vraćaju u ravnotežu, podstiču ispravno funkcionisanje i samoisceljujuće procese i tako dolazi do poboljšanja. Ono je uočljivo, izrazito efektno deluje!
Preporučuje se serija od tretmana, sa razmakom najbolje od nedelju dana između svakog od njih. Reč o metodu isceljivanja, koje pokreće samoisceljivanje.Izuzetno je važno, možda i ključno, ne da verujete,ili ne verujete u ovaj metod , već DA IMATE JAKU VOLJU da dođe do ozdravljenja, ili poboljšanja zdravlja!
Kako će delovati pojedinačno zavisi od pojedinca, do pojedinca. Većina osoba, koje žude za ozdravljenjem što vise, to delotvornije dožive isceljivanje . To dovodi do toga da odmah nakon prvog tretmana dolazi do osetnog poboljšanja, a, pronalazeći i delujući na uzroke, uklanjaju se energetske nepravilnosti, vraćaju u ravnotežu, podstiču ispravno funkcionisanje i samoisceljujuće procese i tako dolazi do poboljšanja. Upravo je to ono što ovaj nacin isceljivanja čini tako efikasnim.Neko pokazuje odmah nakon prvog tretmana znatno poboljšanje, a kod nekih osoba poboljšanja se javljaju postepeno, kroz vreme.Takođe, osoba ne mora da veruje da će joj tretmani pomoći da bi osetila dobrobiti.Isceljivanje teslinim talasima je “metoda” za poboljšanje psiho-fizičkog stanja osobe, koja pomaže da dođe do bržeg i uspešnijeg izlečenja

ISCELJIVANJE TESLINOM BIOENERGIJOM

Kod ličnog isceljivanja teslinim talasima koriste se potpuno iste frekvencije kao kod tretmana grupnog isceljivanja, samo postoji razlika u nameni i postupku isceljivanja, koji je ovde namenjen pojedincu.Namena isceljivanja je isceljenje na svim nivoima: na fizičkom, mentalnom, emotivnom.Često pitanje koje mi postavljate je :Šta se to događa prilikom ličnog isceljivanja teslinim talasima.
Događa se da se tretiraju određene tačke i energetski meridijani na telu klijenta, sa amerom, da se stimulišu energetski tokovi duž njih i da se povežu sa energetskim linijama Zemlje i Univerzuma.Smisao leži da dođe do poboljšanja našeg psiho-fizičkog stanja, da krene proces samoisceljivanja i to prirodnim putem, jer se koriste talasi koji su iz prirode, a koji su tu i radi toga da se omogući da dođe i do našeg svekupnog ličnog napretka. Namena je isceljivanje da se pomogne osobi , kojoj se radi lično isceljivanje i da upozna bolje i ostvari sve svoje potencijale, jer se osoba povezuje I sama sa sobom. U nekim slučajevima se pojavi miris, koji takođe ima isceliteljsku ulogu,ili pak zvuci, muzika.Ova metoda između ostalog pruža osobi kojoj se radi isceljivanje mogućnost da dođe do boljeg izbora pri odlučivanju, veću sposobnost da pokazuje osećanje ljubavi, koje se usled negativnog iskustva često blokira, jer postoji sumnja I strah od toga . Isceljivanje pomaže da se nakon tretmana osobi omogući da otvoreno I lakše daje I prima ljubav, ili da se oslobodi
osećaja krivice, zatim nekih potisnutih strahova. Doprinosi da se osoba manje sukobljava sama sa sobom I drugima. Neke osobe koje su imale blokiranu kreativnost postaju kreativnije. Ono što je izuzetno važno I što se kod nekih osoba događa je da otkriju smisao sopstvenog postojanja, da im život dobije smisao, ako ga do tada nisu imali. Događa se da prestaju unutrašnje blokade koje sprečavaju osobu da uživa u sadašnjem trenutku, I da lakše prevazilazi negativnosti u sebi, kada se one pojavljuju. Brže se oporavlja od upala, usled unutrašnjeg mira kojeg lakse stiče, mogućnost da se razboli je smanjena. Iscelivanje omogućava osobi da se uzdigne na viši energetski nivo, da sama u sebi aktivira proces dovođenja u stanje unutrašnjeg sklada,

Talking about penises and erections, is it just me or does Vardenafil really suck so bad as opposed to similar meds, because few people are willing to share so intimate problems with doctors. A blood or bleeding disorder, as well as VGR written there, biochemically it blocks the, in order to be able to prevent the problem. For women Cialis or one of the other alternatives which contain a proven DNP5 inhibitor can make a lasting and positive difference to personal relationships. Maybe it is better to try visiting another place, neither Kamagra nor original one, you should carefully read the precautions.

O MILICI
Jos za vreme studiranja fakulteta za sport i fizicko vaspitanje, zbog problema sa hormonima,
od najboljeg prijatelja dobija informaciju o nekakvom detoks programu, nakon kog joj se zivot u zdravstvenom smislu promenio 100%.
Krece da eksperimentise na polju ishrane, isprobavajuci na sebi razne programe i pronalazi se u biljnoj ishrani.
Na ideju da se upise na institut prirodne medicine i zapocne pravljenje biljnih tinktura dolazi pre godinu dana kada je njenoj mami bila zakazana treca operacija stitne zlezde,
koja nakon detox programa nije odrzana. To joj je bio jos samo jedan znak da je na pravom putu i da samo treba da nastavi da prati svoj osecaj, kao i do sada.
Na prvoj godini fakulteta završava kurs za fitnes instruktora-demonstratora.
Nedugo nakon toga, dobija ideju za svoj koncept kome daje naziv “Totalna transformacija tela”
koji počinje da vodi u 3 fitnes centra sa još jednom koleginicom.
Motivisana željom da stalno uči, pohadja kurs za pilates instruktora, koji joj pomaže da ode na Bliski Istok, u daleki Kurdistan, Erbil.
Tamo stiče dodatnu praksu u radu sa decom koju obučava plivanju,
izmedju ostalog i devojcicu sa parezom leve strane tela koja je uspesno naucila da pliva nakon samo mesec dana.
Bila je trener plivanja unuka bivšeg predsednika Iraka Džalala Talabanija i personalni trener njegovih roditelja Qubad-a i Sherry Kraham Talabany
i mnogih poznatih porodica poput porodice Barzani u vladi Kurdistana.
U toku dugogodisnjih istraživanja dolazi do zaključaka koliko je sve u sportu povezano i koliki uticaj ima jedno na drugo,

Za uspeh na ovom fizickom nivou potrebni su Vam ljudi, za uspeh na svim ostalim nivoima potrebni ste sami sebi!

Prijava je obavezna !
