They were definitely geeking out on something! I had this piece of visionary poetry in my dissertation:

I entered - where - I did not know,

Yet when I found that I was there,

Though where I was I did not know,

Profound and subtle things I learned;

Nor can I say what I discerned,

For I remained uncomprehending,

All knowledge transcending.

NB “ecstasy” as we know it did not exist in the 16th Century 😂
