Krishna, the Supreme Person is the origin of all dharma, the essence of all Vedas, and the meditation of all great authorities who understand the absolute truth. By practicing the yuga-dharma (spiritual practices for the specific yuga), everyone will attain the highest satisfaction of soul, mind, and body. Krishna and His holy name are non-different. His name is all-powerful, all-auspicious. Simply by chanting the holy name of Krishna, one can transcend the modes of material nature and attain the supreme spiritual goal. Kali Yuga, the age of quarrel and hypocrisy, that is marked with violence, deceit, and overall spiritual degeneration is the last of the four ages (Satya, Treta, Dvapara, and Kali). In this age of Kali, there is no means of attaining salvation other than chanting the holy names of Lord Hari.
harer-nama harer-nama harer-namaiva kevalam
kalau nasty-eva nasty-eva nasty-eva gatir anyatha
(Brhad Naradiya Purana)
In this age of Kali the only means of deliverance is chanting of the holy name of Lord Hari. There is no other way. There is no other way. There is no other way.
Hare krsna hare krsna krsna krsna hare hare
Hare rama hare rama rama rama hare hare
Iti sodasakam namnam kali kalmasa nasanam
Natah parataropayah sarva vedesu drsyate
(Kali Santarana Upanishad)
The sixteen syllables of the Hare Krishna Mahamantra: ‘Hare Krishna Hare Krishna Krishna Krishna Hare Hare, Hare Rama Hare Rama Rama Rama Hare Hare’ destroy all inauspiciousness in this age of Kali. This is the verdict of the Vedas.
