Here's an idea that came to me:
Make a little poppet of some sort of him. Place it on your altar, or other place given to pensiveness.
For a few weeks, speak
from your Highest Self to his Highest Self via the poppet. Also write
things to it, and place the writing beneath it. Get it all out of your system! Laugh. Cry. Be angry. Be lusty. Whatever strikes you.
Write your intention to hold to your integrity in the situation (as reflected in your desire that it "remain professional"), as well as your desire not to be a hindrance of him holding to his integrity, as well.
Speak to his ancestors, and to yours --our ever-present elders. Let them all know your inner battles, and request their assistance and strength in the situation. I know from your past posts you resonate with Ganesh and others from the Indian pantheon...get them in on this working, as well.
Finally, once you feel you've truly gotten it all out, send the poppet back to the spirit realm in your own fashion, whatever form that may take (i.e., for instance, doing a cut and clear spell, somewhere in nature, during a waning moon perhaps, or whatever you feel would help you "let go").
And so it is. Hope that helps.
[Geez, why is it I can think of things like this for other
people so easily, but not for myself
?! There is a situation right now in my
life where this little working would really help me, in fact, a couple situations. I guess that's why it's great we have a community here: when we help others, we also help ourselves, lol.]
