May his name be praised – for what?

“If not for your sake then for ours”
I still haven't received an answer: Why, for example, in the prayers of the High Holy Days, do we not stop praising Him? Likewise in the blessings of the fathers at the beginning of Shemona.
If He exists – then why does He need this.
Psychologically, I understand that we, Elly, need to know that there is something above us and not slip on the slippery slope of ‘I and the power of my hand’ – But, please give me your opinion, as you do, regarding my question that is disturbing my peace.

I didn't understand what I didn't answer.

Who are we to determine that He does not need our praise? It is embarrassing to assume that God (even when it is a theoretical term and the perception of His existence is a psychological need of man to believe in something greater than life, especially in times of distress). Is the role of the believing man (based on what? Raised on the knees of faith and performing the commandments of learned people) to acknowledge gratitude (what are manners and manners here) to his Creator (who said?) and to improve his misery (as in the Kabbalah, according to the interpretation of ” will be praised” and so on in the future tense – you caused there is a void here before us – you must praise yourself and magnify yourself in the future – because you messed up here).

I didn't understand what was written here. Not even a word.

Why do we praise him? Does he need it?
Why do we strive to please him?

I haven't seen anything new here that I haven't answered.
