Embark on an inward journey of self-discovery and transformation with psychedelic sacraments.

Our program offers breakthrough, life-changing experiences with 5-MeO-DMT, Psilocybin, and Kambo in a safe and luxurious setting right here in Austin, Texas.

“During my bufo experience, at one point, I say, ‘I am fucking REBORN.’ And I can honestly say I haven’t stopped smiling since I left. The weight is gone, the anger is gone, the 500-pound weight on my shoulders is gone. I have never been more clear and happy in my entire life. I’m smiling just typing this. God was right there with me, telling me it’s okay, child; I’m with you always; it’s okay to let it go. And I did. Words can’t explain this experience. It has changed my life; that’s a fact. All of you just being who you are helped me on my journey. I can’t wait to see you all again and just hold you. Love every one of you.”

“I can’t capture in words the life-changing events that happened at the Atma retreat but I will try. I went to this event wanting to know all of who I am. A lifetime of trauma left me feeling like I was never good enough like I always missed the mark. I had recently had a lot of change and didn’t know if I was succeeding or failing in life. I was hoping to walk out of this retreat with some guidance, I walked away with so much more. This retreat healed parts of my soul that had been hidden for a very long time. Now, I feel so loved, worthy, and worth it! No more shrinking when walking into a room. I am so grateful for all the love that was put into making these 4 days happen, every part of it was healing. I’ve walked away with a new family and a whole lot of love. My biggest thanks and love to Whitney and every single person who was there sharing space with me!”

3 years completely clean

I came to face a lot of blocked trauma and in preparation I felt as if there were a lot of heavy things that I had not yet seen that were needing to show themselves in order for me move forward in healing. During my mushroom journey, I began to see some dark things so I became curious about them. Followed them. I told myself that I was going to surrender to these dark things and allow for them to show me what I need to see. As soon as I surrendered I was overcome with the most bright and heavenly light. I experienced the same with Bufo.

In these journeys I experienced my version of heaven…. I did more healing in 4 days than I have done in a collective 10 years. I realized I had already done so much healing which ultimately prepared me for the most beautiful rebirth full of divine light, love and goodness. I am abundantly blessed and forever changed.”
