When communicating with the Gods, it is recommended to perform the ritual of the corresponding God, and after that, by visualizing the Sigil, recite a prayer.
I recommend that you compose your own prayers in your own language, rather than just using templates.
Wherever you are, you can always visualize the Sigil of God and say a prayer to yourself, out loud, or in your mind (if you can't talk).
The Gods will always hear your prayer, do not hesitate!
