Offerings are what we offer for aid from the powers that be.
An offering is anything offered as a gift in exchange for one. A traditional offering is a libation, called nectar -milk, honey, and wine (or juice). This is left for them. An offering can be any Correspondences, Mars would like red masculine things, Venus feminine green things and so forth. So for the Goddess, on a full moon, a white flower, or crescent shaped cookie can be offered. Food for the gods, we all like sweet things. Nothing can be gained less somethings given in return.
