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 given to Chaitanya Mahaaprabhu and that he got absorbed in Jagannaath Jee. But there are some incoherencies also which create doubts in their originality.

Bhaaratee

(Chap 12) Brihaspati Jee said to Indra - "Hey Devendra, In earlier times, there lived a Daanav named Hirbu. He was the descendent of Nikumbh and was brave like Indra. He did Tapasyaa for 100 years and got the Var to be immortal. After getting Var he defeated Devtaa and inhabited Daitya in Swarg. Seeing this condition of Devtaa Naarad Jee suggested them to worship Shankar Jee. So they started doing his physical worship. After 11 years of worship Shiv appeared as Jyotirmaya Ling and started burning Daitya, then Brahmaa Jee pleased him with Saam Sookt. When Soorya entered in Mithun Raashi (Gemini Sign), Brahmaa Jee appointed him as the Lord of Lunar system. The same Mahaa Rudra was born as the son of Saadya Karmaa on Himaalaya Parvat and got famous as Bhaarateesh. Later he also became the disciple of Shankaraachaarya."

Naath Sharmaa

Brihaspati Jee further said - "Maya Daanav had a son named Maayee. He did severe Tapsayaa standing on one leg for 1,000 years. Pleased with his Tapasyaa, Brahmaa Jee built three cities for his enjoyment - 16 Yojan wide gold city like Swarg, one Yojan wide silver city like Bhuvar Lok, and one Yojan wide iron city like Bhoor Lok. Now 1 billion (100 Crore) Daitya started living in those three cities. They took Yagya share so they became like Devtaa and because of not getting Yagya share Devtaa became weak. So Devtaa went to Vishnu and prayed. Hearing Devtaa Vishnu was born as a Bauddh, son of Ajin Braahman. In Taamas Manvantar (4th Manvantar - the present is the 7th one) all the three Varn (Braahman, Kshatriya and Vaishya) became without Ved, without Karm and detached. As the 16th Kali Yug came, they all stopped doing Yagya. Thus the Daitya of Tripur didn't get Yagya share and so started troubling human beings. In the end of the Kalp all human beings got destroyed afflicted by Daitya.

When Sat Yug began, people worshipped Shambhoo. He again assumed the form of Jyotirling. Seeing him Devtaa became happy and they built a chariot from the essence of land, two wheels from the essence of Soorya and Chandra, flag from the essence of Sumeru Parvat and offered to Shiv. Brahmaa himself worked as his Saarathee (charioteer). Four Ved became its four horses. His bow was from the essence of Lokaalok Parvat and was known as Aajagav. When Shiv wanted to pull its string, the bow broke. Vishnu got surprised to see this so He built a Divine bow from the essence of Swarg, named Pinaak. Rudra pulled its string, but it was sturdy so it didn't break. Since then Shiv got known as Pinaakee. Shesh Naag became its string, Indra became its arrow, and Vishnu sat on that arrow. This bow and arrow killed millions of Daitya and Shiv burned Tripur. When Soorya entered Meen Raashi (Pisces Sign) Brahmaa appointed Pinaakee Mahaa Rudra as the Lord Lunar system and all Devtaa got established as before."

Soot Jee said - "The same Pinaakee put his part into the mouth of a Machchhand (It seems that this is the history of Naath Sect) named Yogee in Haridwaar. Naath Sharmaa was born from that Tej. He was very bright and learned. He also won all learned people and came to Kaashee and became the disciple of Shankaraachaarya."

Kshetra Sharmaa

Brihaspati Jee said - "Devendra, Braahman born in Bhrigu Vansh were killed by Kshatriya born in Taaljangh in Kurukshetra in the 12th Dwaapar of Chaakshush Manvantar (the 6th Manvantar). Taking the wealth of those Braahman, Kshatriya became the friends of Daitya. At that time some Braahman's wife remained pregnant for 100 years. The child couldn't tolerate so much time so he came out of the womb by bursting her thigh. The whole world started burning with his Tej, so all Devtaa came to him to pray. The child threw that Tej in water. Jal Devee (water goddess) drank that Tej assuming the form of Vadavaa (mare), but she also could not keep it, so she vomited it. Brahmaa Jee kept it deep into the sea under Trikoot Parvat. When Soorya entered Mesh Raashi (Aries Sign), Brahmaa Jee appointed it as the Lord of Lunar system in the form of Rudra. Because he was born from thigh that is why he was called Vorv, because he burned the world he was called Dahan, and because he was vomited by Vadavaa he was known by the name of Vaadav."

Soot Jee said - "The same Dahan produced Tej from his mouth the same got famous as Kshetra Sharmaa, the son of Saaraswat Braahman of Kurukshetra. He was very learned. He got defeated by Shankaraachaarya, so he became his disciple."

Dhundhiraaj

Brihaspati Jee again said - "Devendra, In earlier time, when the world was drowned in water and Brahmaa's 100 years have also passed, Tamo Gunee Mahaa Kaalee appeared alone. Then she changed into Mahaa Gauree. Now she had five faces, ten arms, and three eyes. Her name was Shivaa. She saw the minute Tej which was there in all the directions, from her third eye. She tried to take it but could not succeed, so she saluted Him with her five mouths. Pleased with her prayers He entered in her five mouths. The same Brahm assumed the form of a man and got known as Swaayambhoo. From Him was born 18 armed Mahaa Lakshmee. She started protecting the world. Swaayambhoo got surprised to see her beauty. He entered her taking various forms but He could not find her limits. Because of being huge and taking many forms, he was called Brahmaa. He got tired and came to Satya Lok. He then prayed Shankar.

Then he got busy in creating many things - rivers, riverlets etc. Mahaa Lakshmee got surprised to see the creation and said - "There are many people here, how can I count them?" Hearing this Brahm got divided in two parts - Raktaang from front part and Gauraang from the hind part. Both had four arms. Raktaang was called Ganesh and Gauraang was called Niranjan.

Once Shiv worshipped Ganesh. Ganesh asked him to ask for a Var. Shiv asked him to be born to him as their son. So Ganesh Jee was born to Paarvatee Jee. All Devtaa came to have a Darshan of him. Soorya's son Shani Dev also came. As he cast a glance at him, the child's head was beheaded. That beheaded head stays in Chandra Lok and throws light on Prithvi for 27 days. Shani Dev joined a one-tooth elephant head onto his headless body. Brahmaa, at Paarvatee's request, put Karkat's head on beheaded elephant's head and made Karkat headless. Thus Gajaanan Ganesh was born. Ganesh produced a Skandh from his mouth, the same Skandh was born in a Braahman's house in Kaashee and got famous by the name of Dhudhiraaj. He wrote "Jaatak Aabharan" of "Phalit Jyotish" and became the disciple of Shankaraachaarya.
