These gatherings are a time for reflection, meditation, and celebration of the changing phases of the moon, as well as a time for communing with nature. 
During these gatherings, Wiccans may engage in rituals, spells, and other spiritual practices to honor the moon and connect with the divine. 
Esbats are also seen as an opportunity to work magic, as the energy of the full moon is said to be particularly powerful. 
When esbat rituals occur during a NEW MOON (also known as a dark moon), it is an occasion to worship the darker aspects of witchcraft. 
The FULL MOON esbat tends to be a frenetic celebration. Spells for wholeness, children, mothers, families, clairvoyance, and love are performed."
