is bleach episode 41 filler?

Inside a secret room within Sōkyoku Hill in the Seireitei, Ichigo Kurosaki rests on a mat surrounded by a healing field as Yoruichi Shihōin, and when Ichigo opens his eyes and realizes he is not dead as he wonders where he is, Yoruichi approaches him while noting that he is awake, leading Ichigo to realize that Yoruichi saved him and thank the latter, only for Yoruichi to assert he should thank his own incredible life force for allowing him to survive his wounds.
