SB 1.1.14
apannah samsrtim ghoram
yan-nama vivaso grnan
tatah sadyo vimucyeta
yad bibheti svayam bhayam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Living beings who are entangled in the complicated meshes of birth and death can be freed immediately by even unconsciously chanting the holy name of Krsna, which is feared by fear personified.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Vasudeva, or Lord Krsna, the Absolute Personality of Godhead, is the supreme controller of everything. There is no one in creation who is not afraid of the rage of the Almighty. Great asuras like Ravana, Hiranyakasipu, Kamsa, and others who were very powerful living entities were all killed by the Personality of Godhead. And the almighty Vasudeva has empowered His name with the powers of His personal Self. Everything is related to Him, and everything has its identity in Him. It is stated herein that the name of Krsna is feared even by fear personified. This indicates that the name of Krsna is nondifferent from Krsna. Therefore, the name of Krsna is as powerful as Lord Krsna Himself. There is no difference at all. Anyone, therefore, can take advantage of the holy names of Lord Sri Krsna even in the midst of the greatest dangers. The transcendental name of Krsna, even though uttered unconsciously or by force of circumstances, can help one obtain freedom from the hurdle of birth and death.
