Are you afraid of establishing Ritual? Do you feel that if you create a reason for doing something then you have to continue it forever...and that sort of commitment frightens you?
Rituals don't need to be set in stone. In fact the ritual you set now won't be the one you need later. Rituals work to establish a base of stability, and from there you are able to see clearly what lies ahead and your next step becomes more evident.
A ritual of selfcare is a fluid, changeable, evolving thing. To begin it may be purely for physical or philosophical reasons, and then changes manifest which align you with the next option open to you. Emotional and spiritual requirements come up and it's in these avenues of thought and feeling we truly begin to understand the purpose of what we are and what we are here for.
