Repetition of the Holy Nam means calling upon the Lord, the Satguru. And once this Nam Simran becomes sincere, earnest, untainted by any selfish motives and desires, pure mental vibrations, holy thought currents flow uninterrupted and rush forth towards the Holy Feet of the Lord who also then hurries up with outstretched arms to clasp the devotee in His Divine Embrace. This is the magic of Prema Bhagti, Love-divine, pure and earnest Nam Simran.
