(Chap 47) Krishn said - "Now I tell you about Saptamee Vrat.
In Maagh Maas, on the 7th day of Shukla Paksh, worship Soorya Bhagavaan with the name of Varun. Next day, on the 8th day, feed sesame seeds, jaggery, and fried wheat flour mixed with sugar to Braahman. This gives the fruit of Agnishtom Yagya. 
In the month of Phaalgun, on the 7th day of Shukla Paksh, worshipping Soorya gives the fruit of Vaajpeya Yagya. 
In the month of Chaitra, on the 7th day of Shukla Paksh worshipping Soorya with the name of Vedaanshu gives the fruit of Ukth named Yagya.
In the month of Vaishaakh, on the 7th day of Shukla Paksh worshipping Soorya with the name of Dhaataa gives the fruit of Pashubandh Yaag.
In the month of Jyeshth,, on the 7th day of Shukla Paksh worshipping Soorya with the name of Indra gives the fruit of Vaajpeya named Yagya.
In the month of Aashaadh, on the 7th day of Shukla Paksh worshipping Soorya with the name of Divaakar gives the fruit of Ukth named Yagya.
In the month of Shraavan, on the 7th day of Shukla Paksh worshipping Soorya with the name of Maataapi (Lolaark) gives the fruit of Sautraamani named Yaag.
In the month of Bhaadrapad, on the 7th day of Shukla Paksh worshipping Soorya with the name of Shuchi gives the fruit of Tulaa Purush named Daan.

In the month of Paush, on the 7th day of Shukla Paksh worshipping Soorya with the name of Bhaaskar gives the fruit of many types of Yagya.

Thus keeping Vrat for one year, one should do Udyaapan. Draw a Mandal of red sandalwood paste of one, two or four arm length and make Soorya Mandal from red vermilion and Geroo inside that Mandal. Worship Soorya with Dhoop and variety of Naivedya. Keep pitchers full of grains and gold in front of him. Give 1,000 Aahuti with sesame seeds, jaggery, Ghee and Aak's sticks with the Mantra "Aa Krishnen..." (Yajur Ved, 33|43). Feed 12 Braahman and give them red cloth, one cow with calf, umbrella, shoes, and Daksinaa. After all this one should eat himself also quietly.

Whever does this Vrat with this method, he becomes healthy, good speaker, handsome, and long lived. Who keeps fast on the 7th day he gets freed from all sins and lives in Soorya Lok. Thus Devarshi Naarad says."
[This Vrat is found in Bhavishya Puraan, 1/20 also but with a different flavor]

Kalyaan Saptamee Vrat
(Chap 48) Krishn said - Whatever 7th day of Shukla Paksh falls on Sunday that is called Kalyaan Saptamee or Vijayaa Saptamee. On this day take bath with cow's milk mixed water, put on white clothes, make a lotus flower of eight petals with rice. Then worship those petals with these eight names starting from eastern petal and going clockwise - Om Tapanaaya Namah, Om Maartandaaya Namah, Om Divaakaraaya Namah, Om Vidhaatre Namah, Om Varunaaya Namah, Om Bhaaskaraaya Namah, Om Vikartnaaya Namah. Worship the Vedee with white cloth, fruits, Naivedya, Dhoop, flower garland, jaggery and salt and Mantra which end with Namaskaar. After this do Havan and feed Braahman to his capacity. Donate a sesame seed pot with gold to Guru. Next day take Kheer with Ghee with Braahman. Thus one should do this Vrat for one year and do Udyaapan in the end by donating water filled pitcher, Ghee pot, fold, clothes, jewelry, and cow with calf. If one cannot give so much then donate only cow."
[This Vrat is found in Matsya Puraan, Chapter 74 also in similar Shlok]

Sharkaraa Saptamee Vrat
(Chap 49) Krishn said - "Now I tell you about Sharkaraa Saptamee Vrat which is the giver of long life, health and wealth. In Vaishaakh Maas, on the 7th day of Shukla Paksh, one should take bath with the water with white sesame seeds, and put on white clothes. Make an eight petal lotus flower with stem with Kumkum (red vermilion) and worship Soorya Bhagavaan with the Mantra "Savitrey Namah". Fill a pitcher with water, put a pot filled with sugar on it. Adorn the water pitcher with red cloth and white flower garland. Keep a golden horse also near them. Then do Aavaahan of Soorya with this Mantra. (see p 426) After that do Jap of Saur Sookt, or listen to Saur Puraan (Bhavishya Puraan). Next day, on the 8th day, in the morning worship Soorya Bhagavaan and give all material to Braahman and feed him with sugar, Ghee and Khee. He himself should eat food without salt and oil.

Thus one should do this Vrat for one year, do Udyaapan by donating a full bed, milk giving cow, a pitcher full of sugar, fully furnished house, and a horse made of 1,000 or 100 or five nishk gold to one's capacity. This Vrat gives the fruit of Ashwamedh Yagya. It increases the number of children and all kinds of calamities quiet."

Kamal Saptamee Vrat
(Chap 50) Krishn said - "Now I describe you Kamal Saptamee Vrat whose even name pleases Soorya. In Vasant Ritu (in Maagh Maas), on the 7th day of Shukla Paksh, take bath with the water with yellow mustard. Keep sesame seed in a pot and draw a lotus flower in it. Imagine Soorya in that pot and cover that pot with two clothes and worship it with the following Mantra. (see p 427) Then give that pot to a Braahman after worshipping him. Next day, on the 8th day, feed Braahman to one's capacity and himself too without oil. Thus one should do this Vrat for one year on the 7th day of Shukla Paksh of every month.

At the end of the Vrat, one should donate golden lotus flower, golden cow, many pots, Aasan, lamp and other materials to Braahman. Who ever does this Vrat with this method, he becomes very prosperous and lives in Soorya Lok."
[In several essays and Puraan, this Vrat has been listed as Kamal Shashthee]

Shubh Saptamee Vrat
(Chap 51) Krishn said - "Now you listen to another Saptamee that is called Shubh Saptamee. After keeping fast on this day one becomes free from grievances, diseases and sorrows. In Aashwin Maas, on the 7th day of Shukla Paksh, one should invite a Braahman for Swasti Vaachan. Worship a cow with this Mantra. (see p 427) Put one Ser (900 gms) sesame seeds in a copper pot and then establish a golden idol of bull on it and worship it with cloth, flower garland etc. In the evening all should be given to Braahman saying "Aryamaa Preeyataam". In the evening eat Panchgavya and sleep on naked floor. Next morning, on the 8th day, worship Braahman. Every month one should give two clothes, golden bull, etc. At the end of the year, sugar cane, jaggery, clothes, pots, Aasan, full bed, a copper pot with one Ser sesame seeds, golden bull should be donated saying "Vishwaatmaa Preeyataam". Who does this Vrat thus, he becomes prosperous, is worshipped in Dev Lok for one Kalp. After he is born on Prithvi and becomes Chakravartee king. This Saptamee destroys hundreds of sins.
