9. The upper world is included in the secret of the letter Yud OF YUD HEI VAV HEI, WHICH INCLUDES ARICH ANPIN AND ABA AND IMA, NAMELY the first upper dot, WHICH IS ARICH ANPIN that emerges from the concealed, the hidden and that which is not known and is not known at all and will not be known. It ascends by MEANS OF the secret of infinity, THE PARTZUF OF ATIK, and from this concealment, FROM ARICH ANPIN, shines a thin and hidden light WHICH IS SUPERNAL ABA AND IMA THAT HAVE TWO ASPECTS OF YESOD, 1) A NARROW PATH AND 2) A CONCEALED WAY, including in itself the generality of all the lights. And in this concealed WAY, THAT IS IN ABA AND IMA, one strikes it who did not yet strike BEFORE, WHEN IT WAS IN SUPERNAL ABA AND IMA. That which did not illuminate in him now illuminates in him. It then produced one light, which is a delight of delight (NAMELY CHOCHMAH OF CHOCHMAH), AND IT IS for pleasure, and to hide the thin light, which is concealed in that light.
