An Tairseach, the Irish word for “threshold,” marks a meeting place between worlds—a space where awareness deepens, and the spirit can be encountered more clearly.
Join Colin Bates and David Schiesser for a rare residential immersion in County Sligo, Ireland, hosted at the stunning Temple House.
This historic Georgian mansion, set within a 1,000-acre estate, offers sweeping views of the surrounding landscape and the evocative lakeside ruins of a 13th-century Knights Templar castle. Take a tour.
There are places where the veil feels thin, where stillness carries presence, and where time seems to soften. County Sligo is one of those places.

Medianità in trance Un’Immersione Profonda nella Trance, nella Medianità Evidenziale e nel Lavoro nel Cabinet
Inclusa l’immersione e l'esperienza nel Cabinet Sitting
NOCERA UMBRA - ITALIA
Esistono luoghi in cui lo sviluppo interiore si vive in modo diverso.
Nel cuore dell’Italia, a Nocera Umbra, nasce uno spazio di armonia, fiducia e profondità spirituale, in cui è possibile rilassarsi davvero e lasciarsi andare. Quando questo accade, la trance si approfondisce in modo naturale.
Questa settimana propone un viaggio che unisce Medianità Evidenziale, trance e lavoro nel cabinet, includendo l’esperienza diretta del cabinet e l’esplorazione della Medianità Fisica all’interno di un percorso strutturato, protetto e sostenuto.
Non si tratta semplicemente di un corso, ma di una vera immersione nella trance e negli elementi della Medianità Fisica, fondata su sicurezza, integrità e supporto autentico: le basi ideali per sentirsi accolti mentre si esplora la ricchezza della medianità in trance.
Durante il percorso lavoreremo su:
✨ Comunicazione in Trance
Lo stato di trance diventa un ponte per connettersi con i propri cari a un livello più profondo rispetto alla medianità evidenziale, creando momenti intimi e significativi tra il consultante e lo spirito, ricchi di presenza e connessione.
✨ Parlare in Trance
La fusione con il Team Spirituale viene rafforzata affinché la comunicazione possa fluire con naturalezza e maggiore intensità, imparando a fidarsi dell’abbandono, mantenendo radicamento e stabilità.
✨ Guarigione in Trance
La connessione energetica si amplia per permettere alla guarigione di fluire con chiarezza e intenzione, rafforzando la relazione con il Team Spirituale e favorendo un allineamento più profondo con se stessi.
🌟 Una caratteristica speciale riguarda gli aspetti della Medianità Fisica e il Cabinet Sitting
Sono previsti interventi e conferenze dedicati a questo affascinante ambito, insieme all’opportunità di lavorare e sedere nel cabinet in un contesto rispettoso e strutturato.
Durante la settimana sarà possibile:
• ricevere insegnamenti dedicati sulla Medianità Fisica
• vivere un’esperienza di Cabinet Sitting guidata e supportata
• apprendere come mantenere armonia, pazienza e abbandono
Questo rende l’esperienza davvero unica.
Guidati dall’esperienza, sostenuti con il cuore
Unisciti a Colin Bates, Edel Karis e David Schiesser per vivere un’autentica immersione nel tuo percorso personale, per esplorare la tua profondità ed espanderti con delicatezza oltre ciò che credevi possibile.
È anche un’occasione per sostenere gli altri nello sblocco del loro potenziale, all’interno di uno spazio di cura, comprensione e guida radicata.
E soprattutto è un modo per aiutare il Mondo Spirituale a trovare espressione nel nostro mondo in maniera responsabile, equilibrata e profondamente umana.
Perché quando ci abbandoniamo in sicurezza....
quando ci fidiamo davvero....
quando ci riuniamo in armonia….
qualcosa di straordinario si manifesta.....
e la magia diventa possibile ✨

Ouvert à toute personne désirant explorer ou approfondir ces thèmes.
