‘Nirvana is not a place! Rather, it is simply a view! Remember what the Indian Buddhist philosopher Nagarjuna said: “Between samsara and nirvana, there is not the slightest thread of difference.” The only difference is in one’s perception of it. Viewed with attachment, our world of experience is samsara; viewed without such attachment, it is nirvana.’ (from Lion’s Roar)
‘Those who have great realization of delusion are buddhas; those who are greatly deluded about realization are sentient beings.’ (Genjo Koan)
I am sure there are other words from Dogen that illustrate the first point, but this was the one that came to mind.
