Shrimad Bhagwat, also known as Bhagwat Purana, is one of the greatest Puranas in Hinduism. It is the most sacred book of Hindus and is highly revered by the devotees of Lord Vishnu. It is a book about Narayana, his avatars and the detailed account of Lord Krishna.
Written by Rishi Vyasadeva, the book consists of eighteen thousand verses, which are presented, in twelve cantos. It is believed that Shukha Mahamuni (Son of Ved Vyas) narrated Bhagwat Purana during sarpayaag performed by King Parikshit (grandson of Arjuna). This ancient book is comprised of Mahabharata (Krishna avatar), Ramayana (Rama avatar), and Narasimha avatar of Lord Vishnu among others.
Goswami Shri Tulsidasji provides many comparisons to Ram Katha. Ram Katha is a chintamani (wish-fulfilling gem); it is Kamdhenu (the wish-yielding cow of heaven).
‘Ram Katha sur dhenu sam sevat sab sukh daani.’
A cow has four legs (charan), hence Ramayan consists of chopay (verses). We keep cows to milk them (known as dohan in Hindi), hence Ramayan consists of dohas. In between the verses there are dohas, cchands and sortha.
Ram Katha in this age is Kalpataru (wish-yielding tree that satisfies all the desires of the person sitting under it), also known as Kalpavriksha. In the Shrimad Bhagavat, the Vedas have been called Kalpataru.
Ved is a Kalpavriksha; Ram Katha is Kalpavriksha. This therefore means that Shri Ram Katha is the form of Ved.
