The world becomes delightedon hearing the kirtana of Lord's name andfame.
One who chants sri-hari-nama is worshipable in the world.Chanting hari-nama destroys prarabdha-karma (the results of past pious or impious activity which is now bearing fruit).
Hari-nama can yield all kinds of benefits.One who hears sri-hari-nama becomes liberated from hell.
Hari-nama-kirtana is more glorious and beneficial than studying the Vedas. Performing hari-nama is better than visiting all tirthas - Skanda Purana
Sri-hari-nama is the only method for those who have no way.
Sri-visnu-smaranam destroys all sins but is attained only after much endevor. Visnu-kirtana, however, is superior because the same benefit is attained simply byvibrating sri-nama upon one’s lips.
Simply performing kirtana of Sri Hari’s Nama in Kali-yuga gives the same results as those that are achieved by meditating on Bhagavan in Satya-yuga, by worshiping Him with great yajnas in Treta-yuga, and by performing formal Deity worship in Dvapara-yuga.
