How so?

Yeah, so they go, I mean, this, I suppose, takes us back to 11th and 12th centuries, even slightly before the Sengoku, these new forms of Buddhism coming in.

Nichiren is one, you've got sort of pure land traditions, which become really important in Sengoku, Japan, to maybe come back to those.

I think for Nichiren, what marked it out, Nichiren-shu, I should say, but the founder, Nichiren, what marked it out and what marked him out was a sense of having Japan's destiny firmly in his sights in a sort of political and in a foreign policy sense.

You know, a lot of these other Buddhist sects are far more concerned with the big cosmic picture there, with the afterlife, etc.

Nichiren had a lot to say about Japan itself.

And in particular, a lot of people found this fascinating about him, an eventual cataclysm.

Why was the third unifier, Tokugawa Ieyasu, why was he successful? How did he ensure lasting change when the others didn't?
