What do we learn from "Al Shakai Tis'anag"?
1.
Divrei Eliyahu (25): Your pleasure will be in Him, like "v'His'anag Al Hashem."
2.
Malbim: Your Oneg will not be physical, rather, spiritual. The Nefesh will cling to Hashem, its strength. You will understand that all worldly matters are worthless. Spiritual reward of the Nefesh is primary.

How will you raise your face to Eloka?
1.
Rashi: You will not be ashamed to lift your face to Him to request your needs from Him (Divrei Eliyahu - at all times).
2.
Malbim: All your intents will be to Eloka. You will not desire bodily needs, only to fulfill Hashem's desire and cling to Him.
