Reflection and Discernment

What am I Discovering?

A Place to Begin

I choose one placement that sparks my curiosity. I explore its interpretation, connect the themes with a lived experience and consider what feels meaningful to explore next.

I use astrology as one perspective among many to reflect on my lived experiences, recognize patterns and explore possibilities.

These questions are here whenever I want to return to curiosity and decide what meaning I carry forward.

What themes resonate with my lived experiences?
Where do I notice these energies in my relationships and choices?
What am I learning about how I respond to challenges and opportunities?
How might I integrate what feels meaningful to me?
