To play a video game even with your child, you should know about it first. Then you gotta practice it otherwise you may teach wrong rules of the game. Then you teach about winning. Life is full of this in everything. Be it education, games, marriage, relationships, etc. If you know about it, practice it, become a veteran and then teach. So learning is important by books or teachers, practicing it and trying to perfect in that is next, testing your skills is next. All these things are also applicable in spiritual. Sadhana is practice. Continue with it to reach perfection. Give as many tests to know your worth. Someday you will see the light.
