Mesora

What does Mesora mean?

I know it means following the tradition of our fathers and grandfathers. How far back does it go? Is it only for yekkis who keep things like the Rama for 500 years? What about chasdim that changed many minhagim? So is it perhaps 200 years?

Take skver for example, it has a rich 200 year tradtion going back to chernoybel. But most and many of its followers come from ahskenz oberlanbder backgrounds. The dayan R Nieshaltz is that too, So if you are a skverea with ahskenz grandparents whats your mesora? Are you doing like your grandparents? could you just stop wearing teflin c moed, daven sefard etc.

What about a new chasidus like emunas yisroel? Does its style become mesora?
What about Vein that now davens sefard in most places, wears shtriemls, eats in beis haknesis waits for 72? Is that now its “mesora”?
How about Satmar? Yes the reba zya was a ruv in a town and traces back to the ytev lev. Its chasidus really started in the USA. Is that mesora?
Skver and Satmar now make campfires on log baomer. years ago they mocked it. Is this now a “mesora”
Granted that some like the sanza rebas, Ger Belz or chabad tace back 250 years but many don’t.

I won’t even get into that the whole not mishing on pesach stems from the olden days when there wasn’t normal hashgachas and many in town weren’t religous so you didn’t eat by your neighbor. Yes things also weren’t as controlled and mix ups occurred more often. Now it became a strict “mesora”? Some chasdim today had clewan shaven grandparents who weren’t even as strict.

I recentley read a tumelit about singing new songs by the seder. So whats mesora? The shumel kunda daynau but not shweky vhia shmuda? (Shmuel kunda zl was a great man and tzadik so this isn’t intended to knock him cvs)

I’d love to hear what mesora really means? Please be emes to yourself
