Regarding your question about Govinda Ganamrta, Govinda is Krishna, and ganamrta means the nectar of songs. That means anything sung about the activities of Govinda is nectar. You have mentioned that Srila Rupa Goswami has introduced this. Srila Rupa Goswami, assisted by all other Goswamis have left immense literature for singing about the glories of Govinda. Whatever literature we are presenting, following the footsteps of Rupa Goswami and the others, they are also Govinda Ganamrta. So the more Govinda Ganamrta or the glories of Govinda will be spread the more the nonsense of impersonalism and monism will be defeated.
