Jai Shri Krishna !
“Yadayada hi dharmansya glanirbhavti Bharatam
abhuytthanam adharamasya tadatmaanaam srajamyham
paritranayaye sadhunaam vinashya duskritam
dharmsanstha panarthya sambhavami yuge yuge…”
The complete Shloka, english translation goes…….
“When ever and where ever there is a decline in religious practice,O descendent of Bharta, and a predominant rise of irreligion-at that time I descend myself to deliver the pious and to annihilate the miscreants,as well as to re establish the principles of religion,I myself appear millennium after millennium “.
Happy Krishna Janmashtmi !!
