According to Osho, Jesus' baptism by John symbolizes a voluntary death: the surrender of resistance, ego, and past identity. John initiated only those ready to be drowned - ready to let go utterly - so the old self could go down the river. Through this symbolic death, a new center is born, shifting one from the world of dreams to truth, enabling life from a fresh, divine nucleus.
It means choosing to let your old, stubborn self die so a new, truer you can be born.
