Judah Hayyat, commentary on Ma‘arekhet ha-’Elohut (Jerusalem, 1963), 96b

Jewish Mysticism
I say this may be the matter of the four who entered Pardes. Even though Rashi, blessed be his memory, explained this literally for they ascended heavenward by the power of the name which they mentioned, according to my humble opinion the Pardes is the thoughts of their hearts for they imagined in their minds divine matters until it seemed to them as if all these things were revealed before their eyes so that they saw them with their eyes.
