Mythological image can only be known through experience. Religious form of Yamunaji is visible to all.
Yamunaji is the melted form of Bhakti Rass liquified image. She had flown on the earth for the benefit of its disciples to have Bhakti Bhav.
Yamunaji had emerged from the heart of Surya Narayan and landed at Mount Kalindi. Third beloved of Krishna is “ Ananya Purva ” a daughter of Rishi who did Katyani Vrat. On the contrary Radha with the strength of Bhakti and Samarpan makes atma meet parmatma. Dhara takes away the being from Lord Shiva due to its TRIGUNATMA character. Radha is the First beloved of Shri Krishna (Radha is the reverse of Dhara). She is the fourth patrani of Krishna but Yamunaji the daughter of Surya is beloved of Shri Krishna and not the wedded wife. Yamunaji is the “ISHT DEVI” of Pushtimarg. She is symbol of Mukti from the evils of Yam and light. Shri Yamuna is the daughter of Surya (Sun) and sister of Yam. Shri Yamuna is the fourth element of Shrinathji.
