Shri Ram Prashna Shalaka is part of Shri Ram Charit Manas by Saint Goswami Tulsidas. It is also called shree ram shalaka or sri ram shalaka. In the table shown in Application, each small square is part of a couplet which reveals answer to your question.
Pray God or Diety in your mind and click on any of the letters square. Then your answer will be displayed with the couplet (in Hindi - chaupai). It is recommended to ask question with full faith. In some way it is similar to Horary Astrology or Tarot Card system.
