You are sovereign ruler over your aura or spiritual body, and giving it attention supports the physical and mental immensely. If you read cards casually or professionally, caring for yourself as a channel includes clearing the tendrils that attach to your oracle and tarot decks.
Energetic self-care is honoring that we have fields of subtle vibrational experience that deserve attention. Our emotional, physical, and energetic bodies are intertwined. When we acknowledge the energetic body with a practice, we serve the emotional and physical as well.
