Jedi embrace all cultures. In the event of an unplanned death of a Jedi on a planet where they do not live, the Jedi are happy to embrace local customs. A good example of this is Qui-Gon's death, where his funeral followed the Naboo customs.

My friend Braigwen has expanded on Jedi death, funerary, and mourning customs over on their site. They write, "When a Jedi dies, their eyes should be open. It is the opposite of closing someone's eyes after death; their eyes should be open to the Force."

"Jedi should also take their last breath on the exhale rather than the inhale. If one doesn't manage it and there's another Jedi there, or someone else who happens to be somehow aware of the tradition, they will breathe out on their behalf. It's so that they've given more than they've taken."

"A Jedi is also meant to die with a recitation of the Code complete. This is also usually finished on their behalf, so that they get to 'there is no death, there is the 'Force'."

"It's meant to not be a big deal when Jedi die without those things, and/or their bodies can't be retrieved, but it inevitably is for their loved ones."

"There is a lot of secrecy around what happens with lightsabers especially, but also robes and bodies themselves, to prevent graverobbing (which is just part of how Sith function at this point). Generally, nobody leaves an assembled lightsaber with a body, but often the crystal and parts are left with them (sometimes just the crystal). It's very, very rare for their crystal to be used by someone else or kept for any reason - it's considered akin to necromancy. Necromancy is a huge taboo among the Jedi, because it is using someone else's soul to bind them when they should have been released into the Force."

"Anything they had that isn't their kyber crystal and basic robes are redistributed in a systematic way designed to ensure nobody can create relics or hold onto someone's things as unhealthy rather than healthy grieving."

"Jedi are burned or buried; the deciding factor is generally what's more practical, including with to their own cultural practices from their homeworld. Both options involve the physical form returning to the Force, just at different speeds."

"Jedi mourning periods have no set date, but Jedi are encouraged to come out of self-isolation, if that was part of their mourning, after two weeks and then until it has been a year and/or there is significant concern about them, at which point they are strongly encouraged."

"Jedi carry some reminders, whether it is wearing a small amount of their clothing in a certain colour, or an attitude about a particular topic their loved one cared about, with them for as long as they need to, which can be for the rest of their own life. However, it's very taboo to go "all-in" with mourning, to change everything about yourself to reflect your loved one, because that is also regarded as a form of attachment to them that harms them, you, and the Force spiritually."

(thank you Braigwen!)

This gave loved ones time to say goodbye, pay a visit, and do one final act of care. Then, the body was transported to the crematorium by mortuary workers.

Cremation took place within two days of death, a custom that came about before refrigeration of the body was available. This created an idea of an acceptable timeline for disposition, as it was seen as disrespectful for the body to be left to decompose.

Cremation took place in retort (cremation machine) and lasted approximately two hours. The end result was brittle bone fragments, which would be ground down and mixed with mortar and Ferrix dust. This would then be pressed into a funerary stone which wasinscribed with their name as well as date of birth and death in Bazeese script.

Following the creation of the brick, there would often be a funeral procession from the deceased's home to the location where the brick would be placed. The scale of this procession depended on the person. There would often be an honor guard and band. On the day of the ceremony, the stone would be received by a person close to the deceased, usually a family member or close friend if one wasn't available.

Often, a holorecorded "Truth" would be broadcast for the crowd. Classic Ferrix funeral marches would play, while passers by would stop and stand to pay their respects. Upon reaching the location where the brick would be set, the procession would form around the holoprojector broadcasting the Truth while chanting "Stone and Sky"; silence then befell upon the crowd as the deceased's word "lifted" them. After the ceremony, the funerary stone was placed in a city wall, as the deceased metaphorically "gave their body to support those who remain".

Upon completion of a cremation, ashes were retrieved and scattered in natural area so that the body and spirit could be returned to the planet. Often, funeral temples were located in areas near natural bodies of water, so that the ashes could be scattered there. The Theed funeral temple included a bridge over the Solleu river, where family members of the deceased could scatter the ashes. Due to the length of an open-air cremation, this often took place the following morning at dawn, and was not a public event. Rather, a select few family and close friends came back for this part of the ritual.

The Naboo believed that the "death day" of their loved ones were significant. It was common to spend a death day each year with family and friends or even alone, typically taking the day off of work or school. On death days, the bereaved would travel to the place the ashes would scattered and share prayers or thoughts with thir loved one, hold a memorial meal, and light candles.
