You should have a white candle and a gold candle on your altar. Burn sandalwood and/or frankincense incense.
"Oh God of life and light
Look upon me with favor today
Shed light upon me
Disperse my forebodings
And make me light of heart.
I center my thoughts upon the light.
Make your light to shine upon me and mine.
Make nothing or dark or threatening survive in your light
I pull my curtains so your light can shine in.
I go to let my face glow in your light.
I carry it with me.
