A Sound That Stills the Mind and Awakens the Heart. TUESDAY, August 18, 2026 at 7:00 PM Kromberk Castle Amphitheater. You are warmly invited to an evening of profound relaxation, resonant vibration, and inner harmony. For the very first time, the transformative frequencies of the gong and sacred mantras are joined by the soulful voice of the violin. Sound here is more than music—it is a living vibration that gently guides us back home to ourselves. The interplay of sacred gong frequencies, the delicate resonance of the violin, and the subtle power of ancient mantras creates a sanctuary of harmony.
