Help with 道本

[mxian]

I understand 道 = "tao, the way" and 本 = root, the bottom part of a tree. So,

道本 = foundation of tao or root of a tree.

But I've just heard someone mentioning that 道本 is also a book. So, does that mean 三道本 = 3 books. If that's true, can 道本 be any book, or must it mean a book about tao (道)?

Please help clarifying this. Thank you in advance.

道本 >> path + principle, as in:

1.立身行道, 经世致用的根本 《周礼》

2.儒家思想与主张的根本 《汉书》

3.道家思想与主张的根本 《门论》

4.真性：本来面目 《万教丹经》

《十道本》京剧 (Peking Opera play) >> Tudou + Jingjuok
