I am interested in knowing stories of various ancient Rishis and hence I sometimes look for those stories from Puranas and Itihasas. I had watched Ramayana TV series in my child hood. Recently government decided to re-telecast this series on DD National. While watching Ramayana, I found that after leaving Ayodhya, Rama entered in forest and met various Rishis. Episodes show his meeting with Bhardwaj, Atri, Sharbhang and Agatsya Rishis successively and it is said that Rama met many other Rishis. But names of those Rishis are not mentioned.
I want to know which are all those Rishis? It may be possible that Ramayana does not record every meeting of Rama with all Rishis but I am interested in extracting details as much as possible. So, an answer listing (names) of all Rishis citing some authentic source (e.g. Valmiki Ramayana) would be useful.
