Our purpose

Why we do this work

Our purpose is to reconnect people to themselves, to each other and to nature. We support people through healing, trauma release, exploration of the unknown, non-ordinary states of consciousness and shifts in perspective, and we encourage the exploration of inner creativity and personal development.

We want to raise consciousness to create a better human experience, to build community, and to contribute to the debate on the safe use of psychedelics through carefully held, legal wellness retreats.

Our vision

What we are building

  • A safe, legal container

    A platform for self-exploration, held in a supportive, non-judgemental and transparent way.

  • Inner transformation

    Personal breakthroughs, self-growth, creativity and inner healing.

  • Reconnection

    To ourselves, to each other and to nature.

  • Leadership in the field

    To be world leaders and pioneers in psychedelic therapy and facilitator training.

  • Wider consciousness

    To contribute to the evolution of global consciousness.

Our roots

Imbas Forosnai

Visionary inspiration

In ancient Ireland, the filí, or poet seers, practised a ritual called Imbas Forosnai to reach visionary inspiration: an altered state that enlightens.

The ritual is thought to have involved psychedelic mushrooms. At Inwardbound we see our work as remembering our own ancestral, Irish, indigenous tradition of psilocybin use for visionary inspiration and healing.

After a long colonial legacy of disempowerment, we are reclaiming part of our indigenous Gaelic culture, our ancestral memory and our tradition for ourselves.
