From a lecture of some gaudiya preacher :
After leaving Svananda Sukhada Kunja the yatris had the fortune to take darsana of Hari Hara Ksetra. There, Lord Visnu and Lord Shiva are seen in one deity, which is half black and half white, and both are performing kirtana to Gauranga.
So if Harihara is performing kirtana to Gauranga that means that Gauranga is superior to Harihara .
So if Harihara is none other than Vishnu and Shiva combined , we can then take the logical deduction that Gauranga is superior to Vishnu and , yes , also to Shiva ...
