1. The Lord is on my head like a crown, and I shall never be without Him.
2. Plaited for me is the crown of truth, and it caused Your branches to blossom in me.
3. For it is not like a parched crown that blossoms not;
4. For You live upon my head, and have blossomed upon me.
5. Your fruits are full and complete; they are full of Your salvation....
There are some obvious parallels and correlations I can draw here with the Tree of Life. The Crown as Kether, "other", yet part of the self, where lies the Lord as seen in profile (Kether being the "anchor" of the Lord, or the Malkuth of Him).
The blossoming of the branches can allude to the outpouring of light to form the other Sephiroth in the ToL, each a branch blossoming out. They blossom in us because the ToL is in us, and we are in it ("As Above, So Below", etc.). This is a simultaneous truth.
"It is not like a parched crown" can suggest that it is not a normal kind of crown, not just a piece of gold to serve as a jewel. It is a living thing, a seed that blossoms forth.
The "fruits" could refer to the Sephiroth, each of which is "full and complete" in and of itself, and all of them offer the truth of Kether (and beyond it) through its particular guise, all offering the salvation of Gnosis, this spiritual knowledge that we can find in each Sephiroth, each Navitoth, and all the "nooks and crannies" that make up the spiritual map of evolution.
This is just the Qabalistic "analysis", of course. I encourage others to share their thoughts and musings.
