"There is no vow like chanting the holy name, no knowledge superior to it, no meditation that comes anywhere near it. It gives the highest result. No penance is equal to it, and nothing is as powerful as the holy name.
"Chanting is the greatest act of piety and the supreme refuge. Even the words of the Vedas do not possess enough power to describe its magnitude. Chanting is the highest path to liberation, peace, and eternal life. It is the pinnacle of devotion, the heart's joyous proclivity and attraction, and the best form of remembrance of the Supreme Lord. The holy name has appeared solely for the benefit of the living entities as their lord and master, their supreme worshipful object, and their spiritual guide and mentor.
"In spite of the influences of Kali-yuga, whoever continuously chants Lord Krsna's holy name, even in sleep, can easily realize that the name is a direct manifestation of Krsna Himself."
—Srila Bhaktivinoda Thakura, Saranagati (quoted from Agni Purana)
