As mentioned in the kalisantarana upanishad, Narada mahamuni ask Brahma what is the path for liberation of jivatmas in kali yuga. Brahma's reply is chant the name of Narayana and on further request of Narada, Brahma gives the names of Krishna and Rama and the end result is the hare krishna maha mantra.
Are the names, Rama , krishna indirectly refer to Narayana? Is there any interpretation of gaudiya vaishnava acharya's of these names in the maha mantra if they refer to Narayana.
If reaching Krishna's goloka is the ultimate goal, why do japa on other GOD's names? How is this interpreted or confirmed
thanks
Krishna Vyas
