An opinion of Dr.KariGari 2

 It may be difficult to understand Kuukai buddhism who was a priest in Heian period . 

 He lived from 774 to 835 , and he stayed 2 years in China and he introduced "Dainiti Nyorai" who was over all buddhist .

 When he died , he said "Miroku Bosatu will arrive here after 5.67 billion years . 

 Probably , he might know the multi-universe .

　空海は釈迦如来や阿弥陀如来の上に「大日如来」をセットしたが、これは多元宇宙を知っていたからではあるまいか。
