Synthesis For a Changing World: A Summit & Festival of Synthesis

“Like it or not, everyone is a part of the universal and we must somehow tune in and willingly participate in the rhythms of universal life.”- Roberto Assagioli
The Association for the Advancement of Psychosynthesis (AAP) is delighted to convene this international gathering.
The world is facing significant changes, and we stand at a threshold.
In this moment, we are called to remember our deep belonging—to each other, to the Earth, to the Great Mystery of life. It is essential that we come together to forge powerful pathways of resilience, courage, and kinship; to explore soulful ways to navigate these uncertain times, weaving our shared practices in creativity, wisdom and will towards an emerging vision of a more connected and whole world.
Inspired by the work of Roberto Assagioli, founder of Psychosynthesis, Synthesis for a Changing World invites us to move beyond the familiar patterns and silos of our thinking, training and disciplines. With guests from the sciences, other transpersonal modalities and the wider psychological and psycho-social communities, it is deeply aligned with the three-fold vision of Garrison.
WHAT TO EXPECT
This Summit is designed to identify and address essential questions:
·What is being asked of us now, at this critical time, both individually and collectively?
·What does the future hold, and how can we help shape it?
·What new collaborations may be required in these times, and how do we best support these?
You Will Experience:
·International Presenters & Experiential Workshops
·Psychosynthesis Street Fair, Dialogue Groups & Conversation Circles
·Festival, Arts, Music, Ceremony, and Nature related activities
