I am very pleased to see how nice the book distribution is increasing in Germany. Give those two boys who have done so nicely my thanks. Krishna will bless them: ye yatha mam prapdayante tams tathaiva bhajamy aham [Bg. 4.11]. Krsna becomes more and more pleased by seeing the increment of book distribution. Devotional service is absolute but one who preaches His message becomes very dear to Lord Krsna.
