On days 5 and 6, the people of Guna were immersed in the celebrations of Krishna janma.
Goswami Tulsidasji says in Shri Ram Charit Manas:
Iśvar anśa jīv avinaśī
This is worth keeping in our mind. Do not just see the celebrations of Krishna janma with your physical gross body. See it within your subtle body also. When Lord Krishna was born at Nand Baba. Nand Baba experienced internal happiness and became large-hearted. He called scholarly Brahmins and large heartedly donated a large amount of wealth. This symbolises that when Shri Krishna manifests within one, one becomes Nand (blissful and large-hearted). Let us celebrate Nandotsav through this video clip from the Katha.
