It was initially formulated by the first Ashkenazi Chief Rabbi of British Mandatory Palestine, Abraham Isaac Kook, as a means of unifying Jewish civilization.
"The Holy" - Orthodox Jews, "The Nation" - secular Jewish Zionists, and "The Humanist" - General Humanism found among all peoples.
Kook believed these three forces must work together to ensure the prosperity and security of the entire Jewish community.
Therefore, per Kook, Jewish nationalism and universalism were intrinsically linked together, allowing for the synthesis of these two seemingly conflicting concepts.
