It has been read by me in stories and some news also that the sons of pujaris are llearning the practices by attending the temple work on free hours along with their father. And in the days where the father unable to attend the temple puja, this boy will do the same. In Bangalore I have seen in a Vishnu Temple near KG Road backside, a small boy was doing Archanas and pujas for the devotees, on asking he told that his father was getting fever on that day and when I went there in the evening he was sitting near the shrine entrance and chanting the slokas and mantras with perfect pronouncing and personally appreciated him for his attentiveness. In many places such things are happening but the thing is they should not have that work as profession without going to school. But learning the temple procedures, chanting Mantras, serving the pujari with supply of water etc., reciting slokas are really good to them instead of wavering their mind into television, computer games, cinemas. Through that the whole nation will get cherished as I read in one spiritual book that a seer was worrying about the youngsters not following their rituals and customs according to their own religions and thereby the country losing its status slowly.
