Phoenix's dont exist on the phyzical plane, but you can interact with them on astral plane, or they let some people see them as all spirits do so you can interact with one, but you can't touch one, and spirits are mostly as smart as us, so don't offende them by thinking that they are just animals on the metaphysical planes
Can i ask why you would want a pheonix? I feel like if you beleive in re-incarnation that it may be dangerous to consider one a pet since they are sacred to some people. Even on the astral plane. Would befriending one be beneficial?
Well Phoenix is not a pet or anything like that it's a demon and the legends u heared and read about it all kinda come from the demon called Phoenix xD
For more info u can read a book named the lesser key of Solmon I guess
Don't call any spiritual phoenix,you may end up calling a demon named as phoenix lol. And if you want one perhaps seek one spiritually as a guide can help but physically not possible.Astral projection can be a way.
Astral projection is a mode of travel, period. Destination, however, has made it a game of make believe, with all sorts of magical fake creatures.
Now, about the phoenix, no. You cannot have one as a pet. They don't exist, accept as myth creatures who some people believe to be a creature of destruction, or rebirth, as the story is they reincarnate from their own burnt ashes. So you see why you can't own one.
