Question Detail: I worship only Radha Ji and to a greater extent. Will I still get god-realization or is it mandatory to develop a feeling towards shree krishna? also, what bhavs are applicable to shree radha ji, all of them?Answer:
Radhey Radhey, The topic of Radha Rani is one of the deepest and most difficult to understand. For a brief overview, I would recommend the following 2 minute video: https://youtu.be/lokw_BxmlcI
For a more in depth understanding, please see the two part lecture by Jagadguru Shree Kripalu Ji Maharaj: https://youtu.be/afbE-kMEwTI
. For your brief understanding, I would say that Radha Rani is supreme brahm. She is one with Shree Krishna. She is His female form; or He is Radha's male form.
