Zohar 3:290a (Idra Zuta)

Jewish Mysticism
“Happy is the lot of the one who merits to know His ways and who does not deviate from or err with respect to them, for these matters are hidden, and the supernal holy ones shine in them like one who shines from the light of a flame; these matters are transmitted only to one who enters and exits.”
