The fourth Part of Pratisarg Parv of Bhavishya Puraan is very important with the viewpoint of history. In this part history of all the four legs of Sat Yug, Tretaa Yug, Dwaapar Yug and Kali Yug is given. Besides, the history of the previous births of many Aachaarya, saints, Bhakt poets, is also given. They are said to be the Avataar of 12 Aaditya, 11 Rudra, 8 Vasu, or 2 Ashwinee Kumaar. Special treatment is givento Chaitanya Mahaaprabhu and that he got absorbed in Jagannaath Jee. But there are some incoherencies also which create doubts in their originality.

Raavan

(Chap 13) Soot Jee said - "Hey Shaunak Jee, Bhagavaan Kapaalee Shiv appeared in Kaashee from his part. He was known then as Bhairav and he propagated Aghor path. Then he became the disciple of Shankaraachaarya. He propagated Daamar Tantra (with Mantra)." Brihaspati Jee said - "Maya Daanav's daughter Mandodaree was the sister of the king of Tripur - Maayee. After Tripur got destroyed Mandodaree used to please Vishnu Bhagavaan, so she got good Gati and she got lost in Vindhya etc cave. Two hundred Chatur-Yug period had passed since then. In the 12th Sat Yug of Vaivaswat Manvantar, Pulastya Rishi was born of Brahmaa Jee. He had the son named Vishravaa. Vishravaa Muni did Tapasyaa for 100 years and married the daughter of Sumaalee Daitya - Kaikasee. Kaikasee had two sons - Raavan and Kumbhkarn. Raavan was a devotee of his mother while Kumbhkarn was the devotee of his father. With the desire of Var they both did Tapasyaa for 1,000 years. Pleased with their Tap Brahmaa Jee have them Var of being invincible from Devtaa and Daitya. Then they got Pushpak Vimaan and defeated Devtaa. Devtaa did physical worship of Shankar Jee for 11 years, got Var and became fearless.

Hanumaan

Born from Gautam Rishi's body, Kesaree's wife Anjanaa gave birth to Hanumaan - Shiv's part Avataar. He swallowed red rising Soorya taking it as a fruit. Darkness spread all around so Indra  hit him on his chin with his Vajra. At the same time Raavan also caught him with his tail, still Hanumaan didn't free Soorya. He fought with Raavan for one year, at last Raavan got tired and tried to get free from him. At the same time Rishi Vishravaa came there and pleased Hanumaan with Ved Stotra. Then only Hanumaan released him. After that Hanumaan went to live on the banks of Pampaapur and remained immovable that is why he got known as Sthaanu. Because of fighting with Raavan with fists he got the name Hanumaan. Pleased with Hanumaan's Tapasyaa Brahmaa Jee said - Hey Rudra, listen to me. Bhagavaan Raam in person will incarnate in the 28th Tretaa Yug's first leg. You will be obliged by getting His Bhakti." After this Brahmaa Jee established him as Bhaadrapad Maas' Chandramaa, and got Mandodaree married to Raavan. Raavan became the Digpaal (Lord of Direction) of Nairritya (south-west) direction. Bhagavaan incarnated as Raam and killed Raavan."

Soot Jee said - "The same Hanumaan was born as Baal Sharmaa in Kadalee Van and lived at Manikarnikaa Ghaat in Kaashee Nagaree. He became the disciple of Shankaraachaarya and wrote Tantra-Mantra Shaastra."

Raamaanujaachaarya

(Chap 14) Brihaspati Jee said - In the beginning, a huge lotus flower appeared from the navel of Viraat Purush, from which appeared Brahmaa Jee. He had two arms, four heads and two feet. He thought, "who am I?", "from where I have come?", and "who is my father?". Devtaa sitting in his heart said - "You do Tap." So Brahmaa Jee did Tap for 1,000 years. Bhagavaan appeared before him in the for of a child. Brahmaa got surprised to see that child. Vishnu said smiling, "I am your father." But Brahmaa considered himself His father so they started arguing about this. At the same time Tamo Gunee Rudra Jyotirling appeared. Now Brahmaa in Hans (swan) form and Vishnu in Varaah form went up and down for 100 years that Ling but could not find its end. At last they prayed Bhagavaan Shiv. Pleased Shiv appeared before them and went to Kailaash Parvat. He sat in Samaadhi and five Divine Yug passed like that.

In the meantime, Taarakaasur got the Var from Brahmaa Jee after doing Tap for 1,000 years that he would die only by the son of Bhava. After this he defeated Devtaa and became Indra. Devtaa went to Rudra in Kailaash and prayed him. Shiv said - "Ask a Var." They said - Brahmaa Jee has given the Var to Taarak that he would die only by your son, so please you get married and protect us. In Swaayambhuv Manvantar, Daksh had 60 daughters. Satee was one of them. She did your physical worship for one year and you gave her Var and she got married to you. Her father Daksh insulted you so she immolated herself in the Yagya. The same Satee is now born to Himaalaaya and Mainaa's house in the form of Paarvatee. When she was born, at the same time she became 9 year old. To get you as her husband, she did Tapasyaa for 100 years staying in water, for 100 years staying in Panchaagni, for 100 years drinking only Vaayu (air) and for 100 years without breathing, so now you marry to Shivaa (Paarvatee) now."

Shiv Jee said - "Dev Gan, Your proposal seems unjustified, since my 10 elder Rudra are still unmarried. I am the youngest Rudra - Bhav. How can I marry before them? Second thing is that she is A-Vyakt Roop Ambaa, she is omnipresent, how can I marry mother-like Bhagavatee? Therefore I give you my Tej (Power) for your welfare, it will fulfill your wish." Shankar gave his Tej to Agni Dev and sat again in Samaadhi. Devtaa came back to Brahmaa and reported everything to him. [Brahmaa and Vishnu approached him again] and he gave Var to Paarvatee to marry him. Paarvatee said - "I will do whatever my parents will say, so I need permission from them."

Shankar Jee sent Saptarshi to Himvaan with this proposal and Shankar got married to Paarvatee Jee. Paarvatee used her Riddhi and Siddhi to felicitate her marriage procession. All Devtaa got surprised to see that so they prayed her for their protection from Daitya. She made them fearless. After the marriage Shiv came to Kailaash and enjoyed with her for 1,000 years. Shiv Jee made Kaam Dev as Anang (without body) seeing him daring. He said to Rati - "You will live in beings' hearts. This is Swaarochish Manvantar, in the 28th Dwaapar of Vaivaswat Manvantar you will get Shree Krishn's son Pradyumn as your husband." And Shankr Jee disappeared. (Later Kumaarswaamee Skand was born and he comforted Devtaa by killing Taarakaasur."

Soot Jee said - "Hearing this from Brihaspati, Bhagavaan Bhav took birth in the house of Aachaarya Sharmaa from his part. He got famous by the name of Raamaanuj and was younger brother of Raam Sharmaa.
