In the Kali-santarana Upanishad (1-11), the Hare Krishna maha-mantra is established as the only means of deliverance in Kali-yuga.
In the Gita the Supreme Lord also declares:
patram puspam phalam toyam
yo me bhaktya prayacchati
tad aham bhakty-upahrtam
“If one offers Me with love and devotion a leaf, a flower, a fruit or water, I will accept it.” (Bg.9.26) Therefore the International Society for Krishna Consciousness has many temples all over the world… The functions of the tongue in devotional service are to chant the Hare Krishna maha-mantra and eat prasada that is offered to the Lord. (Srila Prabhupada)
