Yam Puree - - Yam Raaj lives in Sanyamanee Puree and it is located at the south of the Meru Parvat. His court's name is also Pushkamaalinee. In Varaah Puraan, Nachiketaa describes Yam Raaj's Yam Puree like this --
"Nachiketaa replied – “Yam Puree is made of gold and spread in the area of one thousand Yojan. It is well fortified and it is impossible for anybody to trespass its territory. I saw sinners experiencing unbearable torture over there. I also saw couple of rivers flowing there – Pushpodak River, at the bank of which there are trees in abundance and Vaivaswatee River, which flows through the central part of Yam Puree. Vaivaswatee contains divine water which never dries up.

Yam Puree has two entrances – one through which only virtuous souls like sages and hermits are allowed to enter and the second through which sinners enter Yam Puree. The former entrance is such that even heat loses its quality in its vicinity. The latter entrance is situated in the south and has a large iron gate. I also saw three large ditches called Audoombar, Avirchiman and Uchchavach which are meant for the sinners. Sinners are also forced to pass through the flames that continuously keep on erupting to the west of Yam Puree.

"I saw a grand assembly hall where truthful and virtuous people live. It is graced by the presence of sages like Manu, Vyaas, Atri, Gautam, Angiraa, Bhrigu and others. There, I saw a goddess who is worshipped by Yam Raaj. The goddess controls all the functions of the world. I also saw the ferocious Kaal. He possesses extreme anger and is very powerful. Time does not have any influence on him as the result of which he enjoys eternal youth. I also saw various types of demons and giants in the hell.”

"I saw many messengers of Yam Raaj punishing the sinners. Some were beating the sinners with sticks in their hands while some sinners were being forced to enter fire. I saw the entire sinner wailing and repenting for their sinful deeds. Many sinners were kept at a very dark place where there was no light. Those who had committed graver sins were put in boiling oil. I saw many sinners being given all sorts of severe punishment. I saw a place where iron nails were spread all around. This was the place where people who breached the modesty of women were given punishment.”

“Sinners like liars, greedy people, jealous people, calumniators, treacheries etc, go to hell. Similarly, one who kills a child or a woman, or kills a Braahman, or one who criticizes the Ved, or lends money on interest, or one who abandons his parents, or faithful wife, or one who criticizes his Guru, or one who sells liquor, or a Braahman who sells Ved, goes to hell and tastes the fruits of his sinful actions.”

"I saw ten different hells – Tapt, Mahaa-tapt, Raurav, etc; each of the latter is more ferocious than the former. The sinners are sent to all these hells on the basis of the gravity of their sins. Yam Raaj himself instructs Chitragupt on the punishment to be given to these sinners."
