מבחינת גבורות עליונות דבינה עילאה
This derives from the level of the Higher Gevurot of the Higher Binah. In other words, the source of this love is from the level of Gevurah in Binah.
דהיינו, שעל ידי התבוננות בגדולת אין סוף ברוך הוא, דכולא קמיה כלא ממש חשיב
The arousal of this love comes about through meditation on the greatness of the Infinite One, before Whom all is considered as absolute nothingness.
תתלהט ותתלהב הנפש ליקר תפארת גדולתו, ולאסתכלא ביקרא דמלכא
Then, the soul becomes inflamed and flares up towards the precious splendor of His greatness, in order to gaze upon the glory of the King. This is the content of this love.
כרשפי אש שלהבת עזה העולה למעלה
It is like glowing, fiery coals of a mighty flame which surges upward (not a love which is drawn towards some object, but one which ascends with the burning fire of klot hanefesh),
וליפרד מהפתילה והעצים שנאחזת בהן
and it strives to be parted from the wick and wood on which it has taken hold.
In the same way, the soul seeks to tear away from the body, which is compared to a wick (ch. 35) and to wood (ch. 29), in relation to the fire and light of the soul.7
והיינו על ידי תגבורת יסוד האש אלקי שבנפש האלקית
This results from the predominance of the element of divine Fire that is in the divine soul, unlike other forms of love which derive from the element of Water in the divine soul.
