Most of the people today do not tolerate anything connected with spirituality. They feel that technology and scientific inventions are rational one. They want proof for anything and everything. There are certain abstract qualities which can not be proved but it can only be felt by oneself. In that category, Love, Faith and belief systems occupy important positions. Religion belongs to those who have faith and belief in them. Reading a holy book would inspire them though there is no tangible proof for all those things contained in the book. Mother points out the father to the baby. can anybody demand proof? It is absurd. It purely depends upon the faith on one's own mother. Children believe everything they are told. They are innocent and love all and hence they are equated to God! When you fill the vessel with water, there will be sound till it is filled. Once it is filled up, the sound ceases. Until one's knowledge is full, there will be doubts and discussions. Once we become knowledgeable then there won't be any doubt. Likewise those who do not believe in religion tend to criticize them due to half knowledge.
