Kabbalah sur Rois 1 1:54

Have I not said to you, I shall be clear (Ps. 19:14), for he will be a healer (Isa. 3:7)? He who utilizes the Daughter of a Voice will become rich. There is none who aggrandizes himself to say (I Kings 1:5), learn Gemara. And if he is a poor man, he sleeps on his pledge (Deut. 24:12) and rides on a donkey (Zech. 9:9); he glorifies himself in the hidden wisdom and its tumult, and delights in it (Isa. 5:14). There is no spirit within him (Hab. 2:19), and the living will take it to heart (Eccles. 7:2), for with stratagems will we wage war (Prov. 24:6), with a fortiori [reasoning] and equivalent statements in the bundles of Mishnah, and from the desert a gift (Num. 21:18) [by] which man will live (Ps. 89:49), if he will be as a horse or a donkey not to understand (Ps. 32:9) the laws of God, positive and negative. He tells his words; in keeping them there is great reward (Ps. 19:12) to complete their commandments in the most acceptable way.

The second is to be careful with the Awe of God throughout the day. The pious Rabbeinu Yonah wrote, in the Letter of Teshuvah a great pillar regarding this issue in Torah, that all day long the awe of heaven should not depart from before your eyes, as it is written "Do not envy sinners in your heart, but only have awe of God all day long" (Prov. 23:17). And we need to say that the simple meaning of the verse is this, do not be jealous of sinners, rather who should you be jealous of? Of the Awe of God, in the level of Awe of God, meaning, why not be in awe of God all day long since sinners lack [the feeling of] completion as the issue of "and I and my son Shlomo will be sinners" (I Kings 1:21) - "but only have awe of God all day long" - as those who have awe of God all day long, one sees that it is needed to have awe of God all day long. And a reminder to a person who has awe is to use tefilin all day long, if possible, at least on the hours in which one deals with Torah, when they are free from worldly dealings.

Happy are the penitent, who in one hour, one day, one moment, get as close to the Holy One, blessed be He, as most righteous come to the Holy One, blessed be He, over several years. Abraham did not come into the supernal days until he was old, as has been explained. Neither did David, as it is written, "Now King David was old, advanced in years (lit. 'coming with the days')" (I Kings 1:1). But a penitent comes right in and cleaves to the Holy One, blessed be He.
