Today is the appearance day of Lord Balarama, the Personality of Godhead who
is the first expansion of Lord Krsna, the original Personality of Godhead.
As Krsna states in the Bhagavad-gita (4.7):
yada yada hi dharmasya
glanir bhavati bharata
abhyutthanam adharmasya
tadatmanam srjamy aham
“Whenever and wherever there is a decline in religious practice, O
descendant of Bharata, and a predominant rise of irreligion–at that time I
descend Myself.” Lord Krsna says, srjamy aham: “I manifest Myself.”
