Bhatha Prahalada was the son of Demon King Hiranyakashibu. Lord Narasimha killed Hiranyakashibu and made Prahalada as the king of the region. Bhakta Prahalada was an ardent devotee of Lord Hari. He has preached the greatness of Lord Hari along with his fellow students. He has lived a life with much holiness, pure bhakti, and kindness among his people.
During his regime, he has daily offered Annadanam to more than 1000 people. He is the Avatar of Divine Personality – Sangukarna Devar. Sangukarna Devar was serving Lord Brahma in Satyalok during Krita Yoga. Once due to his mistake, he was cursed by Lord Brahma and took the avatar as Bhakt Prahalad.

Sree Bhakta Dhuruva Mahathmiyam
Dhuruva was born to the king Uthanapadha. He was the son of his first wife. The king Uthanapadha was very much attracted to his second wife and was not shown much interest with Dhuruva.

Sage Mirukandu has no child and performed severe penance for several years. Lord Shiva granted him the boon and then Markandeya was born. He was supposed to live only up to the age of 16. After knowing this, young Markandeya left his parents and went to the forest and created a shiva lingam on soil on his own and performed deep meditation on Lord Shiva.
After his time in the earth is over, Lord Yama approached him and tried to put the rope on his neck but suddenly it was struck with Shivalingam. Lord Shiva angrily emerged from the Shivalingam and burnt Lord Yama into ashes. Due to the prayers of divine gods, he gave the life for Lord Yama. And Lord Shiva granted Markandeya the boon for becoming Chiranjeevi – Always 16 and there is no end for his life. He always remains constant. Such a pure Bhakti he observed.
