Kabbalism on The Age of the Universe

Seven Doubles: BGD KPRT
With them were engraved
Seven Universes, seven firmaments
seven lands, seven seas,
seven rivers, seven deserts,
seven days, seven sabbatical,
seven jubilees and the Holy Place...

The days...universes refer to compounded time periods. (They call 'creation' what we call 'universe.)

According to some, this is the 2nd, the 6th, or the 7th creation (universe)

Midrash (R. Iscaas of Acco) says that when counting the cycles

one must not use an ordinary physical year,
but rather, a divine year.
(Otzar Chaim, Trans. (86b))
Based on
A thousand years in Your sight are as but yesterday (Psalm 90:4)
