Once a person came to a wise man ho and asked him a question, "Is it worth praying?"Wise man ho smiled and answered him, "Don't ask such questions. we all pray when there is nothing left. but now you asked I would say if you do pray then it should not be about something you need. if someone need something then that person should try to do it by himself as, it is would be worth helping god by taking some burden off him."Person got bit confused and yet again questioned him, "What is the best way to pray?? what words should we use to pray??"Wise man answered, "I think, it's better to pray from bottom of your heart, then you will know the words."Then wise man said, "Can I ask you a question?"Person nodded in yes. Wise man questioned, "Everyone wants to know how to pray but no one asks about whom??"With surprised look person replied, "It is obvious that people pray about themselves or people close to them."Person continued and ask to wise man, "What about you?? about whom do you pray??" 
He used to pray to god about god.
