XV. Any mundane practices that are associated with this deity?
As far as physical actions go, the first one would be holding the bowl, which is simply holding an empty bowl in this world in order to take Her place in the Cave. Sigyn may request other actions from an individual, but most people tend to suggest holding the bowl to anyone wanting to interact with or do anything with Sigyn.
In a less literal fashion, a person can hold the bowl in more metaphorical ways – helping to support and aid caregivers, being a caregiver, becoming a hospice worker, volunteering to spend time with physically and/or mentally ill patients, volunteering to spend time with people in nursing homes, providing emotional support and resources to those who are mentally ill, volunteering with hotlines, etc.
I currently can’t find the post where I initially shared this site, but emotionalbaggagecheck.com lets you leave baggage or carry someone else’s.
Devotional blog dedicated to the Goddess Sigyn offering support to those who are "holding the bowl" within difficult relationships.
