IMO it should be cyclical. Passion provides ideals and goals, reason can help work towards those but also evaluate them and refine them.
Like once upon a time, I wanted a high end sports car. But over time, through reason, I realized that owning one would be more of a net negative than a positive in many ways and now I wouldn’t likely get one even if it would be trivial to afford. I’d like to not even need a car at all, but reason has me recognizing that that also wouldn’t be a positive given that I live in an area where mass transit infrastructure is poor.
This boils down to having conflicting passions/goals and using reason to resolve them (like wanting a sports car while also wanting to afford other things and to reduce my environmental impact and not driving a sports car is a very easy way, trivial even, to have less impact than driving one).
