Maharal wrote with ruach hakodesh

The Bnei Yissaschar (2:21) writes, “Behold I have brought before you three reliable testimonies that the light of the Chanukah lecht is associated with the or haganuz: the Rokeiach — whose lessons come from Eliyahu HaNavi z’l; the Maharal of Prague Z as known, his lessons were said with ruach hakodesh and that he used Sefer Yetzirah; and from the holy rav, closer to our generation, renowned for his ruach hakodesh, Reb Pinchas of Koritz zt’l…” R' Biderman, Torah Wellsprings, Miketz, 5780
