Murasaki Shikibu assaulted women who worked as Saiin in "The Murasaki Shikibu Diary," but she admitted the polite personality of the Imperial Princess and artistic and mysterious elegance of the imperial palace of Saiin, so from the evidence presented by these two top-level Heian female authors, there was no doubt that it was a cultural salon second to the imperial court during the period of the Imperial Princess.
紫式部も『紫式部日記』で斎院に仕える女房を非難しつつ、内親王その人の人柄のゆかしさや斎院御所の風雅で神さびた趣深さは認めており、平安女流文学の最高峰であるこの二人の証言から見ても、内親王の時代の斎院が宮中に次ぐ文化サロンであったことは疑いないであろう。
