For me, the day-to-day rituals of thankfulness need to be maintained, like daily offerings of (in my case) coffee to the Gods. It is in the home that the rituals become the heart of praxis. It is in the home that the habit of ritual becomes real in our hearts.

Rituals remind us of our connection to the Gods and as such need to be remembered. They help us remember the stories of the Gods as well. They commemorate events that tie us together with the Gods such as the celebration of the Thesmophoria and Heliogenia. (one ancient and one modern as examples) and help us remember that we are part of a greater Cosmos…..
