I do not see why anyone need to feel sad or disappointed that Prasad Ji does not read Tamil.
Even though I read English,Malay,Sanskrit,some Tamil,some Hindi,...I still feel it is a matter of personal interest and knowledge can come from any direction and in any language.
It is no big deal knowing many languages if we do not ever gain any Atma Jnana.
As long the person knows how to save himself from drowning in the Ocean of Samsara that is more than enough.
I am very reminded of this story:
The Learned Pandit
One day several men were crossing the river on a ferry boat. One of them was a learned Pandit. The Pandit decided to discuss the Hindu scriptures with a fellow passenger in order to pass the time and show off his knowledge.
So he turned to one of them and began, �I presume you have read the Upanishad?
The passenger humbly replied, �No Sir, I have not!�
�You didn�t!� said the Pandit in surprise. �A quarter of your life has been wasted!�
�But then you must have read Shashtras!� the Pandit continued.
�No, Sir, I can�t say that I have!� the passenger replied, feeling quite distressed.
�Well then half of your life is wasted!� said the Pandit arrogantly.
�What about the six systems of Hindu philosophy?� asked the Pandit in a final effort to begin an intellectual discourse.
�I am afraid I haven�t even heard of them, Sir!� the passenger replied.
�Not heard of them? Then, my friend, three-fourths of your life is wasted.�
Just as the Pandit said this, he found the boat suddenly began to pitch in increasing violent waves.
�There is a storm and I cannot control the boat!� the boatman shouted. It is going to capsize! Jump overboard and swim to the shore!�
The Pandit looked terrified. �Don�t you know how to swim?� the fellow passenger asked.
�No, I never learnt swimming!� the Pandit moaned.
�You never learnt swimming! Then your whole life is gone, Panditji� the passenger replied smugly as he jumped out of the sinking boat.
So, knowledge derived from books is not enough.
One must acquire practical learning too.
