The very act of engaging in Torah study constitutes one’s intimate attachment to the divine wisdom contained therein.
In that sense, the particular topic of study and the level of depth one delves into it matters less than the basic fact of his involvement in Torah study.
When a person studies Torah, he generates a circuit of divine flow in the world, one of holiness that radiates from the greatest heights to the deepest depths.
Granted, Torah exists in the world even without him, but on its own it leaves no imprint.
Only when a person engages in its study does he create the revelation, as he becomes a medium through which the connection with the Divine Presence is reignited.
