Zoroastrian funerals are pretty different from what's usually found in Western tradition. That's because in Zoroastrianism, the age-old Parsi religion, dead bodies don't go underground; instead, they go sunbathing on what's called a "Tower of Silence." That's weird, you might say. Why would anyone get rid of their dead like that?
The answer makes sense once you're aware that in Zoroastrianism, physical purity and spiritual purity are closely connected. Death is impure by default, as is anything that a dead body touches. In short, Zoroastrians need to dispose of their departed quickly and in a way that defiles as little of the material world as possible. The Towers of Silence work because of the exposure to the sun (but mostly because of the vultures - just like the Buddhist practice of Sky Burial.) Zoroastrians are pretty serious about this ritual, to the point that in the past they've considered it a meritorious action to dig up bodies and properly dispose of them. In locations where burial by exposure is illegal or too difficult, however, Zoroastrians turn to more traditional methods like cremation.
They Feed Their Dead Bodies To Vultures On Top Of Towers
Vultures are a big part of Zoroastrian funerals. All you have to do is set a dead body out in the sun on a Tower of Silence and wait for the vultures, who are known for their efficiency when it comes to getting rid of dead bodies. It doesn't take a gaggle of them very long to reduce a human corpse to a pile of bones - they can do it in an hour or so.
Sure, death by vulture might seem unorthodox, but it's not that bizarre if you think about it. You have to get rid of dead people somehow, and Zoroastrian funerals do it in a way that benefits other living creatures (i.e., giving the vultures an easy meal). In fact, feeding one's dead body to vultures is considered a Zoroastrian's final act of goodness.
Traditional Zoroastrian Funerals Are Banned Almost Everywhere
Towers of Silence aren't anywhere near as prevalent as they were two or three thousand years ago. For one thing, urbanization has made it difficult to continue the practice without upsetting a bunch of non-Zoroastrians in high-rises who insist on complaining about both sight and smell. For another, you can't legally have a Tower of Silence in many Western countries.
In Iran, where Parsi cultures originated, Towers of Silence were banned in the '70s for various reasons. One place remains for a traditional Zoroastrian funeral: India.
Traditional Zoroastrian Funerals Are Legal In Mumbai
India is one of the few places where it's still possible to secure a traditional and legal Zoroastrian funeral.
The main place you can find Towers of Silence is on Malabar Hill in Mumbai, in the middle of a 54-acre garden called Doongerwadi.
The Lack Vultures In Mumbai Causes Issues
There is a slight problem with the vulture solution in Mumbai; namely, there are not enough vultures anymore. A drug called Diclofenac, developed as a painkiller for livestock, ended up accidentally decimating the vulture population in the area before it was banned in 2006. This unfortunate shortage of birds poses a significant problem for Zoroastrian funerals, as it's hard to beat the corpse disposal efficiency of vultures. Other birds of prey in the area can't even come close.
Mumbai's Parsi community is trying to speed things up by installing solar concentrators, which dehydrate dead bodies much faster than the unassisted sun. It's not ideal, but it's better than nothing.
