Krishna is present fully in His holy name and this is realized by the humility and sincerity in our chanting.
In this material world there are only two representatives of the Supreme Personality of Godhead; the transcendental sound vibration of the Holy Name and his eternally transcendental deity incarnation.
The holy name of Krishna has extraordinary spiritual potency because the name of God is nondifferent from God Himself.
Sri Namamrita – The Nectar of the Holy Name,
What is the power of Lord’s name ? The process of chanting the holy name of the Lord is so powerful that by this chanting even householders can very easily gain the ultimate result achieved by persons in the renounced order.
