You can listen whole Bal Kaand here.I like to listen from here and sing myself from the book Ram Charit Manas.
Read Ram Charit Manas
Bal kaand begins with worshipping Lord Ganesha and Lord Shiva. Tulsidasji has narrated Shiva and parvati Marriage events then he started the story of lord Rama's and his three brothers birth and celebrations.This Balkaand ends with celebrations of marriage of all four brothers.This part is very vibrating and full of celebrations.It invokes positive mindset.
