Read manga 370. Yodaime put only some part of chakra. And there was no more explanation about it. Except that Naruto should find some kind of key.
No, when Jiraiya was having a conversation with kakashi after they came back from there 3 year journey, they talked about what it did to him and how it could kill him.
