In the greater cosmic scheme of the universal experience.

The Stoics acknowledged the existence of emotions as much as they acknowledge any other aspect of human existence; they merely argue that emotions should not be allowed to take center stage, so to speak, at the expense of rationality and logic, in the greater cosmic scheme of the universal experience.

I don't understand the bold words. Could you explain it to me!?

I think it means "when the universal experience is considered".

Does it have the same meaning as "in the grand scheme of things"?

Thanks
