What is the difference between doing a spell for love or money
And meditate with the gods for a specific thing
Will the gods spells lead us to achieve something or will they help us directly without doing the spells or rtl?
Or when we are unable to do a mantra due to circumstances, but we can meditate with the gods for a specific thing

If you doing a spell for the first time, do it by yourself - to experience magic on your very own.

You can ask a god to raise the power of your spell - this is beginner/intermediate friendly.
:in this case you should do the spell during/after the evocation.

And if you are more advanced, and you have proved yourself, you can ask a god to manifest something for you like a spell would do.

The differenc is that a god can handle that energy, and will have a higher chance to manifest.
(if you can speak with a god, and you two have consulted the work, it is 100%that it will manifest.)
