Spirit is the ability to be inspired and inspiring unless mathematicians didn't get the memo -

"God is spirit, and his worshipers must worship in the Spirit and in truth.”
John 4

Astronomy is like music, it takes no effort and no notation to enjoy what is in front of people, it becomes a resonance found in the spirited individual hence Pascal's comment that mathematicians look ridiculous when they try to treat spiritual or intuitive matters from the bottom up -

"We must see the matter at once, at one glance, and not by a process of reasoning, at least to a certain degree. And thus it is rare that mathematicians are intuitive and that men of intuition are mathematicians, because mathematicians wish to treat matters of intuition mathematically and make themselves ridiculous, wishing to begin with definitions and then with axioms, which is not the way to proceed in this kind of reasoning. Not that the mind does not do so, but it does it tacitly, naturally, and without technical rules; for the expression of it is beyond all men, and only a few can feel it."
Pascal


Nobody can deny spirit/inspiration therefore the attempt to sound authoritative just looks hapless leaving you all to bite each other based on your own indoctrination instead of relying on your own talents.
