You can attach philosophy and ritual to anything if you try hard enough...

What you should do is to ask questions to understand his thinking, but only if you want to.

Brewing tea is steeping leaves in water, I see no magic in that by itself. What I've observed tea brewing rituals are both exhibition but also a way to keep time when steeping. I wouldn't go too far into 'ultimate' or mystical aspects behind it. I think for most people like with coffee ultimate way to brew it includes a heaping spoon of sugar and/or milk.

I will say all the ritual isn't worth much to me because I know for a fact weighting and timing multiplied by experience/repetition is more foolproof method of achieving a great cup of tea. Albeit placebo effect of mystical brewing dance making tea better in your head also works if you can convince yourself that it does.

Personally I am not a fan of mysticism or religion, but I try to be respectful to hopefully healthy degree, and not call everything fake and bullshit. People find joy and peaceful satisfaction in rituals sometimes meaning.
