To seek Truth is to prefer Being above all else, even in a catastrophic form, simply because it exists.
I am continually with you;
You hold my right hand....
25 Whom have I in heaven but You?
And there is nothing on earth that I desire besides You.
26 My flesh and my heart may fail,
but God is the strength of my heart and my portion forever.
The Tzemach Tzedek writes: The love expressed in "And there is nothing on earth that I desire besides You..."(Psalms 73:25) means that one should desire nothing other than God, not even "Heaven" or "Earth," the highest spiritual planes of the Garden of Eden, for these were created with a mere ray and drop of His Light...
The love is to be directed to Him alone, to His very Being and Essence.
This was actually expressed by my master and teacher, the Alter Rebbe whenever he was in a state of ecstatic clinging to God, unio mystica, he would exclaim as follows:
I want nothing at all! I don't want Your Garden of Eden, I don't want Your World to Come... I want nothing but You alone.
