Now coming to you point of temples being places where you pay to get blessings.
I guess you had some nightmare visiting such type of place. Temple is meant for those whole are deeply in worldly affairs and are not able to completely disconnect from the day to day life.

You don't need to pay to get bless. You need to love God to get blessed. And love for God happens to lucky ones or who initiate there own self on the path of meditation on bramha. Yes this is possible. Passing through the difficulties which come in way of the sadhak as parikshas you attain a state where you receive the showers of ultimate blessing of the bramha.
