Curate, connect, and discover
The conversation between Atsushi and Dazai in this chapter is so important, because this is clearly not Dazai, at least not the real one. The real Dazai is still in Mersault, almost on the other side of the world, this version that Atsushi is talking to is just the same hallucination from the last chapter, a fragment of Atsushi's subconscious taking the form of someone he trusts, respects and admires to give him the information he needs to move forward, even if it is information that he already knows but does not have enough confidence in himself to follow. The conversation at the end of the chapter is not only about the dimension of Ame-no-Gozen, but also about Atsushi himself and his relationship with his past. In order to reach the core of Ame-no-Gozen, Atsushi must learn to navigate between the past and the future, both in the dimension of the divine being and in his own history. I believe that from this, Atsushi will be able to discover more about the tiger and about his own past, perhaps find out something about his parents, and about his connection with the book and Fyodor, but for that to happen he needs to let himself confront his past, and understand (or accept) his place and role in this world.
