Feel welcome to a **small and intimate circle that takes place in a super cozy location.** Carried by the primal beats of the **shamanic drum**, the overtone-rich vibrations of the **multisound instrument**, the rhythmic pulse of **rattles**, and the power of the **voice**, a sacred space opens where you can release, surrender, and realign with your essence. The **Shamanic Sound Journey** will support you to: ✨ Release stress and tension ✨ Enter deep relaxation and altered states of consciousness ✨ Activate intuition and inner imagery ✨ Gain strength, clarity, and inspiration No previous experience is required – only an openness to let the sound carry you. **📍 Location: Samariter Kiez (You will receive the address after registration)** **💫 Energy Exchange: €25 (Bring a friend and you both pay €20.)** **⏰ Please arrive in time.

The evening did me good and I can only recommend it to others.* *Gladly again !!!"* 🙍🏻‍♂ **Alexander:** *„Through this trance, I regained pieces of the puzzle that had been completely forgotten due to life in our society. I can't even put into words what exactly it was, but it was connected to certain memories that I wouldn't have been able to access in my everyday state of consciousness. This deep relaxation gave me the feeling that I could let go of things in my system and it felt as if I had been given a deep massage."*

Hallo, es ist wieder so weit, der zweite Freitag im März ist schon diese Woche. Deshalb habe ich im Neffes am Freitag Abend für uns den hintere Bereich reserviert und ich freue mich schon, euch wieder persönlich zu sehen! Und hier der übliche Ankündigungstext: Unser zweimonatliches Treffen steht wieder an! An jedem zweiten Freitag eines ungeraden Monats treffen wir Selbstständige, Unternehmer und Freiberufler aus der IT uns wieder um 19:00 Uhr im Neffes. Bei einem gemütlichen Zusammensein werden wir uns über fast alle Themen unterhalten. Der Schwerpunkt liegt dabei auf den beruflichen Themen. Z. B. wie gehen andere mit den Kunden und deren Mitarbeitern um, was sind die neuesten Insider Infos von den verschiedenen Unternehmen, wie sieht es bei den anderen mit den Einsatzorten und Arbeitsbedingungen aus und vieles mehr. Es wird wie immer ein interessanter Abend mit einem umfangreichen Erfahrungsaustausch werden, der einen auch beruflich weiterbringt. Mit dem DBITS e.V. wollen wir die Anerkennung von IT-Freiberuflern in der Gesellschaft und Politik vorantreiben. Dort gibt es leider noch einen sehr großen Aufhol- und Aufklärungsbedarf und damit viel zu besprechen und zu erfahren. Des Weiteren bietet uns der Verein ein breites Netzwerk an Leuten mit den gleichen Zielen und Problemen. Aber wie gesagt, das Ziel ist ein schöner, informativer Abend, es gibt kein Mitgliederzwang. Nimm teil, ich freue mich schon auf Dich! Viele Grüße und eine gute Zeit bis zum nächsten Freitag!

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

Das ist zwar der zweite Teil, aber wer den ersten Teil verpasst hat, kann trotzdem teilnehmen. Wir werden wieder spontan ein Thema oder Problem auswählen und dann mehrere klassische Methoden der Philosophie daran ausprobieren. Das heißt, dass der Einstieg diesmal von mir geleitet wird, erst danach kann frei diskutiert werden. Durch diese Herangehensweise sollen den Teilnehmern Werkzeuge zur Handhabung des eigenen Lebens in die Hand gegeben werden. Denn Philosophie geht weit hinaus über Plauderei, heiße Luft oder abstrakte Glasperlenspiele. Philosophieren heißt auf eine bestimmte Art an sich selbst zu arbeiten. Die Veranstaltung richtet sich an alle - Anfänger und Fortgeschrittene. Dieses Event ist auch als Einführung für jene geeignet, die noch nicht viel mit Philosophie anfangen können. Aber selbst Kenner der Materie werden dieser Methodik etwas abgewinnen können. Als ein Werkzeug werde ich auch eine speziell "trainierte! KI anbieten. Wie immer: Schwurbler und Missionare für Rechts und Links-Außen, Esoteriker sowie andere "erleuchtete" Gruppierungen sind hier falsch.
