What does it mean to surrender to God and guru?
Surrender changes you into what you surrender to
Surrender (sharanagati) is like a dacoit giving himself up to the police and then doing whatever he is told. When a devotee surrenders to Bhagwan, Bhagwan's qualities come into the devotee.
In the same way, when a devotee takes refuge in Bhagwan, a disciple in the guru, a son in his father, the father's qualities pass into the son and the guru's qualities into the disciple.
