I very much dislike the term "Force ghost". It's a very commonly used description in the wake of The Last Jedi. I find the term trite when considering modern use of ghost to mean something of frightful fantasy or inconsequential folklore. When Obi-Wan Kenobi gives himself over to the Force in A New Hope he is not dying but rather transforming into a more perfect being. He is merging mind, spirit and energy and leaving his corporeal self behind. Whether or not this transformation is an achievement of Jedi alone or the larger Star Wars universe of souls I cannot tell. It may simply be that only Jedi are advanced enough to come back, so to speak.
Precept 10: The practical Jedi acknowledges and anticipates a higher embrace of existence at the end of one's corporeal journey. This can be contextualized as life after death, soul departure, paradise or nirvana. The currency of this transition to a more understanding form is a simple equation. During the corporeal journey, what one gave minus what one took must be positive to obtain the merger of mind, spirit and the universe.
What can be more practical than that?
