In the words of Thomas a Kempis, from the Imitation of Christ:

"3. Love is a great thing, a good above all others, which alone
maketh every heavy burden light, and equaliseth every inequality.
For it beareth the burden and maketh it no burden, it maketh
every bitter thing to be sweet and of good taste.  The surpassing
love of Jesus impelleth to great works, and exciteth to the
continual desiring of greater perfection.  Love willeth to be
raised up, and not to be held down by any mean thing.  Love
willeth to be free and aloof from all worldly affection, lest its
inward power of vision be hindered, lest it be entangled by any
worldly prosperity or overcome by adversity.  Nothing is sweeter
than love, nothing stronger, nothing loftier, nothing broader,
nothing pleasanter, nothing fuller or better in heaven nor on
earth, for love was born of God and cannot rest save in God above
all created things.

4. He who loveth flyeth, runneth, and is glad; he is free and not
hindered.  He giveth all things for all things, and hath all
things in all things, because he resteth in One who is high above
all, from whom every good floweth and proceedeth.  He looketh not
for gifts, but turneth himself to the Giver above all good
things.  Love oftentimes knoweth no measure, but breaketh out
above all measure; love feeleth no burden, reckoneth not labours,
striveth after more than it is able to do, pleadeth not
impossibility, because it judgeth all things which are lawful for
it to be possible.  It is strong therefore for all things, and it
fulfilleth many things, and is successful where he who loveth not
faileth and lieth down.

5. Love is watchful, and whilst sleeping still keepeth watch;
though fatigued it is not weary, though pressed it is not forced,
though alarmed it is not terrified, but like the living flame and
the burning torch, it breaketh forth on high and securely
triumpheth.  If a man loveth, he knoweth what this voice crieth.
For the ardent affection of the soul is a great clamour in the
ears of God, and it saith: My God, my Beloved!  Thou art all
mine, and I am all Thine.

6. Enlarge Thou me in love, that I may learn to taste with the
innermost mouth of my heart how sweet it is to love, to be
dissolved, and to swim in love.  Let me be holden by love,
mounting above myself through exceeding fervour and admiration.
Let me sing the song of love, let me follow Thee my Beloved on
high, let my soul exhaust itself in Thy praise, exulting with
love.  Let me love Thee more than myself, not loving myself
except for Thy sake, and all men in Thee who truly love Thee, as
the law of love commandeth which shineth forth from Thee.

7. Love is swift, sincere, pious, pleasant, gentle, strong,
patient, faithful, prudent, long-suffering, manly, and never
seeking her own; for wheresoever a man seeketh his own, there he
falleth from love.  Love is circuмspect, humble, and upright; not
weak, not fickle, nor intent on vain things; sober, chaste,
steadfast, quiet, and guarded in all the senses.  Love is subject
and obedient to all that are in authority, vile and lowly in its
own sight, devout and grateful towards God, faithful and always
trusting in Him even when God hideth His face, for without
sorrow we cannot live in love.

8. He who is not ready to suffer all things, and to conform to
the will of the Beloved, is not worthy to be called a lover of
God.  It behoveth him who loveth to embrace willingly all hard
and bitter things for the Beloved's sake, and not to be drawn
away from Him because of any contrary accidents."

Looking at this passage, I cringe to think that in my much worldlier days a copy of this precious book slipped through my hands (and my head) in the first years I began to be home schooled. What a stark reminder of what is robbed from the soul when it is fed on the maxims of the world rather than the word of God... that it looses savor even for words like these, is repulsed by them even. Alas I no longer have my copy, but I heartily recommend anyone who hasn't read it, to go out first thing and get themselves one.

Notice: the lengthy excerpt I quoted was from the Project Gutenberg website... they release as electronic docuмents, I believe those which are now "public domain." Among others you can get this book, and the Summa there.
