Once while taking a bath in shree yamnaji a very tiny divine idol of infant lord Krishna grasped Shri Vallabh's Janoy and told Shree Vallabh to take him out.
Shree Vallabh optained this diety and named it Shree Balkrishnalalji.
Shree Gusainji (Vitthalnathji) when made a partition of his seven devine idols to his seven Sons gave Shree Balkrishnalalji to his 6th Son Shree Yadunathji
Shree Balkrishnalalji depicts the Infant Krishna as mentioned in the (PutnaMoksh lila) of Shrimad Bhagwad
The Gaurshaym (Fair & Dark) image seems to crawl in the lap of Shree Yashodaji and holds a lump of butter in his right hand.
This image of Shree Balkrishnaji has been in Surat since more than 300 Years.
