Intentions are what you hope to get from the journey, what you hope o learn, or why you're participating in ceremony. They can be simple like, "I'm curious to see what the medicine shows me" or more personal like "I'd like to learn how to forgive my father." Everyone has their own intentions while working with the medicine and, more often than not, the medicine will provide you with an experiences that is completely different—causing many dedicated journeyers to declare: "the medicine has intentions of their own."
Setting intentions can be beneficial, especially if you want to use ceremony for healing. However, intentions can also be unhelpful if you're too focused on them or if you set too many. For some, just accepting the experience without setting intentions allows for the medicine to show what the participant needs.
Intention setting can also be a good way to center yourself and relax before a journey. Think about your intentions and explore them by journaling.
