Are you on the square?

Yes, it's certainly possible to anchor one's soul to an object or location. Darth Andeddu did so, I believe, many thousands of years ago, and of course Exar Kun did it with his temple. I've never done it myself: all of my own essence transfers have been from living body to living body. One major point of caution, if you ever go that route: do NOT attempt except with major preparation or at serious need. Ad-hoc binding to an object is possible, and it will let you attempt to possess anyone who touches the object - but if nobody touches the object within a minute or so, your soul will likely dissipate into the Cosmic Force.
Immortality is a very broad topic. If you intend to dabble, talk with me first and I'll steer you away from the traps and pitfalls, of which there are many.
Something a little more practical that may interest you: though it's not among my skills, a colleague on the Pomojema showed me that it's possible to see through the eyes of an illusion. He can create an illusory bird or snake to get a line of sight on something he otherwise couldn't. Fascinating.
