āpannah samsrtim ghorām yan-nāma vivaśo grnan
tatah sadyo vimucyeta yad bibheti svayam bhayam
[Srimad bhagavatam, Canto 1 – Chapter 1 – Verse 14]
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 Krishna, which is feared by fear personified.
Vāsudeva, or Lord Krishna, 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 Rāvana, Hiranyakaśipu, Kamsa, and others who were very powerful living entities were all killed by the Personality of Godhead. And the almighty Vāsudeva 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 Krishna is feared even by fear personified. This indicates that the name of Krishna is nondifferent from Krishna. Therefore, the name of Krishna is as powerful as Lord Krishna Himself. There is no difference at all. Anyone, therefore, can take advantage of the holy names of Lord Śrī Krishna even in the midst of greatest dangers. The transcendental name of Krishna, even though uttered unconsciously or by force of circumstances, can help one obtain freedom from the hurdle of birth and death.
