Acharya Mahapragya said this quote

It is very difficult to understand man. It is also very difficult to understand what a man does. If he is able to give an explanation, it may be easier. Even then everything can not be understood. Words have their limitation and comprehension, its limits. So if we are able to understand 25% of what is being said, even that should be deemed, as good communication skills are very good. Beyond this one should not even aspire for.
