Salute the Spirits

Acknowledge their help in providing the feast before you , and the life we live to enjoy...

Give thanks to the Deities you have invited by offering them food.
Put the offerings on and around the plate of the Spirit

The feast should have a period of silence so that you can contemplate your departed friends and relatives on a personal level. Think of their passing and your hopes for their well being and ultimately a joyous reunion. If someone is recently departed, try to put aside your sadness and think of that soul as well and happy in the presence of the God/dess.
Feel the presence of those who have joined you and rejoice in their presence. Allow them to speak to you of whatever they want to communicate listening and speaking to them in silence.
