Sravanam kirtanam is the beginning - to chant and hear. Book distribution is under this category of sravanam kirtanam. The next item is smaranam. If somebody simply remembers the Supreme Lord, that is also as good as sravanam kirtanam. Then there is arcanam. That is also as good as the others, but one who simply becomes engaged in arcanam and does nothing of sravanam kirtanam, his position becomes in the material field. Any one of the nine processes is as good as the other. There is no question of inferior or superior. But out of all of them sravanam kirtanam is very important.
