Knowledge to Blind

Lord Krishna told Arjun "this knowledge of Geeta should be shared and given to those who value it, who are tapasvi, who have stable mind and body, whose sensory organs(eyes,ears, nose,tongue etc) are within his control and well coordinated. It is most precious and scientific knowledge which guides you to lead a balanced life and helps at every sphere of life.

Ramesh had a friend Ramu who was blind. He went to his Ramu's house and told him to stay with him for sometime. The blind man Ramu and Ramesh stayed together and had good time. It was time for the Ramu to depart. He told Ramesh that he could find his house on his own and he need not take trouble to leave him till his house.

It was getting cloudy and slight drizzle was there so Ramesh told his friend to stay back but the Ramu insisted on going back to his house. Ramesh told him to take lantern as it is quite dark outside. The blind friend said"oh! you are making fun of me. You know I cannot see so what help will I get from this lantern. I can walk with my stick"
Ramesh said "dear friend, if you carry lantern, the other person will not dash against you due to the light from lantern and he can at least see you. Ramu agreed to carry lantern.
While he was walking a man dashed against him and said "are you blind? Can't you see me coming from front? Ramu replied"yes, I am blind but you could see the light from the lantern." The man said "your lantern has no light, it is off" Poor blind man did not know whether there is light in the lantern or no. Anyway he apologised and walked carefully with his stick and reached home.
It is like you try to impart knowledge on a person who does know anything or is not interested in knowing or tries to find fault in it. Try to give spiritual or any knowledge to those who love to hear, read and understand it. Not to the ones who do not value it. It is like giving lantern to a blind man who does not know that the lantern is lit or not.
