Mantra/enn chanting as a form of "offering"

I was thinking about chanting an entity’s name/enn/mantra as a form of “offering”, because while you are doing it you’re focused on that entity so you’re giving a bit of your energy to that spirit.
I thought i could ask something to an entity and then offer some meditation sessions on that spirit’s mantra in exchange. What do y’all think about my ideia?
