Pulooma Son Chavan Rishi, who is better known for creating Chyavanprash. According to Mythology, Bhargava or Parashurama as he is better known was a threat to the Kshatriya Kings who ruled in India during Treta and Dwapara Yuga. The arrival of this warrior class sage to India, was somewhere around the transition period of Treta Yuga and Dwapara Yuga. They have attacked and annihilated the existing Kshatriya rulers of India, as many as 21 times, probably spanning a time period of 1,000 years. The rulers of central India were the major victims of this massacre. The first victim of Parasurama was a ruler of central India, of Haiheya tribe, called Kartavirya Arjuna. Bhargava and Kshatriya were hostile to each other for this many years until they started living in harmony. Bhargavas are a community, who are descendants of Rishi Bhrigu (who contributed in Manu Samriti also) and Parshurama. As per lineage of Bhrigu, described by M.L. Bhargava in his book "Bhargava Jati Ka Itihas", Parshuram was in his 39th generation of Bhrigu and had existed during the period of Bhagwan Ram Chandra and period of Ramayana. Bhagwan Parshuram was known as this, because he was carrying a 'farsa' all the time and used it to kill enemies. Parshuram is also known as 'Bhargava Rama'. Bhargavas became a community after Bhrigu Maharsishi's period and both Bhargava Rama and Bhrigu existed at different times.
