Jewish Mysticism
R. Hizkiyah said- Whoever is occupied with Torah at that hour certainly has a constant portion in the world to come. R. Yose said- What is the meaning of constant? He said to him- Thus I have learnt that every midnight when the Holy One, blessed be He, is aroused in the Garden of Eden all those plants of the Garden are irrigated more from that river, which is called the “raging torrent [Judges 5-21],” the “refreshing stream [Cf. Ps. 36-9],” whose waters never cease. For the one who rises and studies Torah it is as if that river pours forth upon his head and waters him from those plants of the Garden of Eden.
