Secrets of success for indian chess

Clearly, Indian chess is on the upsurge. Plausible contributory factors to this (this poor, cognitively challenged me can think of) might be:

* The inspiration of first Vishy Anand and then Gukesh D. (The effect of Gukesh is probably mostly in the future).

* Stuff that Indian chess is doing better than elsewhere. (I'm looking at Sagar Shah, who I think might be the MVP of organisers all-time).

* Numbers - Jacob Aagaard says that several state championships in India have more entrants than all the FIDE classical rated players.

* I suspect there is a large effect that chess GM is higher status in India than elsewhere.

Am I missing anything?

Anyway, the bit that the rest of the world can learn from is point 2 - stuff that indian chess does better than elsewhere. Does anyone have any info on this?
