Seeing him crying, the devotees reported to Mahaprabhu, 'Mukunda is very sad and he wants to end his life by drowning in the River Ganges. He does not want to maintain his body if he cannot see Your Form. Therefore I have no problem. If I go now I will not be able to see the real Form of Mahaprabhu. Him now, that will not be really seeing Him, it will be illusion.
Real vision is necessary, and that is the main thing.
Mukunda very much chastised himself that he had done wrong, and so had caused Mahaprabhu to at first refuse him entrance. Mahaprabhu then showed His real Form to him. All these are transcendental, therefore we cannot see them with our mundane eyes - that is the main thing. If we go to Vrindavan or stay in Nabadwip the same is true, but still these places are Holy Dhams and they emanate auspiciousness. We can touch a drop of that if we stay there without offence.
