the process of self realization in the age of Kali.

After the reign of performances of sacrifices in the Treta age ,the Dwarpa age heralded the the system of gorgeous worship. However,this did not include the slaughter of animals .According to Srila Prabhupad ,heat,air and the sun togetherwith empirical knowledge were implemented in the worship of the demigods and the fore fathers for the satisfaction of the senses of the individual.The purified saints had already established the worship of Vishnu or service to Lord Vishnu and the way they worshipped the Supreme was according to pancharatric system ,which was the real method of worship.Unfortunately,many other non bona fide successions lapsed to the worship of the demigods.In the beginning of Kali yuga, the Buddhists and the Jains too caused a deviation in the rigid following of Vedic traditions.The influence of perverse age of Kali was another factor in the distortion of the actual pure process of worship.The building of temples to promote worship of Vishnu has generally become degraded to the petty satisfaction of the belly and the genitals of the votaries.For this reason, the acaryas have given the verdict that the process of religion in the age of Kali is by the chanting of the Holy Name
As stated by SriMadhava,In Kali yuga, the process of worship is by the chanting the Holy names of God.'Kalau tu namamatrena pujyate bhagavan Harih'.
The reasona being in this iron age ,there is difficulty in obtaining specific ingredients required for worship as mentioned in the Vedas.Next, there is also the question of the purity of such ingredients for any adulteration is tantamount to offence.The other point is the purity of the mutterer of the sacred hymns and the the clarity of the Sanskrit mantras pronounced in accordance with grammar in order that it will not produce a diverse result.In the chanting of the Name there is no question of proper place ,time and circumstances ,by the mercy of the Lord it is possible in all diverse conditions and there is no barrier in terms of the caste or creed of the individual concerned.
