As per Hindu legend, in the Treta Yuga, Rama (symbol of the god Vishnu), alongside his partner Sita and sibling Lakshmana, remained in the Dandaka woodland as an aspect of their fourteen-year exile. Due to Rama's beauty, a stone transformed into a human called Bhadra, who was viewed as the child of Mount Meru. Devoted to Rama, Bhadra later met the sage Narada, who started a upadesam (guidance) of the Rama Taraka mantra.

 Bhadra interceded and recited the mantra on the banks of the Godavari River for a few years. Pleased, Rama vowed to re-visitation of meet Bhadra when he had discovered Sita, who had been stolen by the evil presence lord Ravana. Be that as it may, Rama neglected to satisfy his guarantee in his lifetime.

Afterward, Vishnu was satisfied with Bhadra's commitment and showed up before Bhadra as Rama. In a rush, Vishnu overlooked that Rama was a human with two arms and showed up with his four divine arms. Rama in upper arms held a shankha (conch) and the Sudarshana Chakra (plate) and a bow and a bolt in his lower hands.

 Sita was situated to his left side thigh and Lakshmana remained to one side. Each of the three confronted west towards the Godavari River. Rama held the conch in his correct advantage as opposed to Vishnu, with the goal of offering salvation to Bhadra.

Rama transformed Bhadra into a hillock; the pictures of the gods in similar stances showed at its summit.[2] The hillock was alluded to as Bhadrachalam or Bhadradri ("Bhadra's slope"). The focal symbol of Rama is alluded by different sobriquets. 

Since Rama plunged from Vaikuntha (Vishnu's homestead) and showed there, he was designated "Vaikuntha Rama". As the god is four-furnished like Vishnu (Narayana), he was named "Rama Narayana". The trio of divinities together implied the parts of the sacrosanct sound Om, which earned Rama the sobriquet of "Om-kara Rama".
