It has been emphatically stated in the authentic scriptures of India that the world will gradually deviate from piety, righteousness, through the four ages - Satya (Golden age), Treta (Silver age), Dvapara (Bronze age) and Kali (Iron age). Satya yuga is adorned with four virtues - penance, sanctity, compassion and truth; Treta yuga is adorned with sanctity, compassion and truth; Dvapara yuga is adorned with compassion and truth; Kaliyuga is only adorned with a very small amount of truth. . Due to the deteriorated state in Kaliyuga, Vedic instructions have lost their adoration and respect. So, ordinary people have the tendency to debate and altercate. According to the eligibility of the people in the four ages, their process of worship was different. In satya yuga, the mode of worship was meditation, in treta yuga the mode of worship was oblation, in dvapara yuga it was sri vigraha archan (worship of Deities) and in kaliyuga – it is harinam sankirtan.

harer nama harer nama harer namaiva kevalam
kalau nasty eva nasty eva nasty eva gatir anyatha
Brhad Naradiya Purana

There is certainly no other way, no other way, no other way except `Harinam' in Kaliyuga.

Namastaka written by Srila Rupa Goswami

‘O Harinam! (Holy Name of Supreme Lord Hari) The Upanishads, the highest philosophical portion of the entire Vedas, the effulgence of jewels, is incessantly worshipping your Holy Lotus Feet by the light of waving lamps. You are also always worshipped by the renowned realised souls Sri Narada and Sri Sukadeva. The transcendental glory of the Holy Spiritual Name is revealed by the tongues of the realised souls who are inclined to serve Him. Therefore, O Harinam! I take absolute shelter to Thy Lotus Feet whole-heartedly.’
