Sri Bhagavan - How Does Repetition God name help Realisation

A devotee asked, “How does the repetition of the name of God help Realisation?”
Sri Bhagavan replied, “The original name is always going on spontaneously without any effort on the part of the individual. That name is aham – ‘I’. But when it becomes manifest it manifests as ahamkara – the ego. The oral repetition of the name leads one to mental repetition which finally resolves itself into the eternal vibration. The mind or the mouth cannot act without the Self.” Thereupon Sri Bhagavan told the following story.

Tukaram, The Great Maharashtra Saint, used to remain in samadhi in the day and sing and dance at night with large crowds of people. He always used to utter the name of Sri Rama. Once he was answering the call of nature and also saying “Ram, Ram”. An orthodox priest was shocked at the uttering of the holy name by the saint when his body was not clean. Hence he
reprimanded him and ordered him to be silent. Tukaram said, “All right!” and remained mute.

But at once there arose the name of Rama from every pore of Tukaram and the priest was horrified by the din. He then prayed to Tukaram, “Restrictions are only for the common people and not for saints like you.”
