Snanyatra & Keri Manorath
Special Snan Darshan at 7:00am - Shringar darshan will not be open to public
The Bhavna of Snanyatra is that, 'Vrajbhaktas' are the 'Jyestha' Bhaktas i.e prime bhaktas of Shree Prabhu. Due to this, Vrajbhaktas does the manorath of 'Jal Krida' with Shree Prabhu with Shree Yamunaji. This manorath took place on 'Jyestha Poonam' thus it is celebrated on this day. Shree Prabhu is in total surrenderence of Vraj Bhaktas who are qualified as 'Jyestha Bhaktas' and thus utsav is also known as 'Jyesthabhishek'.
