Shakti is the father of Parashara and son of Vashishtha. Vashistha is well-known sage, Guru of Sri Rama, seer (द्रष्टा) of Vedic hymns and is among one of Shaptarshi. Parasara is also well-known sage during Dwapara Yuga as well as Treta Yuga. I have heard his story from Ramayana and Mahabharata. He is among one of seven chiranjivi.
I don't know much about Shakti. What I know is just that he is one of the link in Advaita Guru Parampara connecting Vashishta and Parashara.
So, I want to know about sage Shakti (शक्ति). Is there any story or information about him described in Brahmanas or may be in Puranas? and are there any popular works attributed to him?
