About the Podcast

Exploring identity, practicing authenticity and self-love to become undefined
Where is the boundary between our authentic selves and our conditioned selves? How do we shed the definitions society creates to get back to our core self? What does it mean to be true to yourself?

On Undefined, our host, Marisa Tashman, shares her conversations with thought-leaders, change-makers, and passion-players who have journeyed to return to the core of who they are. Together we explore authenticity, identity, core beliefs, definitions, conditioning and societal programming, social justice, relationships, spirituality, mindfulness, wellness, and self-love.

Hi, I'm Marisa (insert wave emoji here). Sometimes I feel like I'm pretending. Don't we all? Avoiding authenticity as a defense mechanism or coping tactic to survive in a society that conditions us to be someone. Classic human. In 2020, amidst the never-ending anxiety and over-purchasing of hand sanitizer/lysol wipes/face masks/shields, I created a podcast called Undefined (naturally came up with the name during a soundbath...totally on brand and not surprising to any of you). Undefined is the embodiment of my exploration of identity - my own identity, my guests' identities, and the identities that are thrown upon us all by the amorphous "them" in charge of our world. As a lawyer (i.e., yet another definition I subscribe to), I investigate facts...but the feelings and the deeper truer parts are often left out. I share my conversation with others who are also exploring these questions. Who am I? Where is the boundary between my authentic self and my programmed self? How do I practice more authenticity? What does it mean to be true to yourself?
