We interpret everything according to our own perception

We hear many things in life, but we do not hear them as they are—we hear them as we are.
Every word is filtered through our own perception and understanding.

We listen to everything and interpret it according to our own perception - our own understanding, and our current state of mind.

Take the example of Lord Krishna’s Updesh in the Bhagavad Geeta.
Three people heard it: Arjun, Dhritrashtra, and Sanjay.

At the end of the dialogue, Arjun bowed down and said:
                   Nashto Moha— Smriti Labdha Tvat Prasadaat Maya Achyuta

                   Sthito asmi Gata-Sandeha Krishaye Vachanam Tava 

                                (Bhagavd Geeta Chapter 18 - verse 73)

      O Krishna - By Your grace my delusion is dispelled, and I am transformed. 

      I am situated in knowledge and I am now free from doubts. 

      I shall act according to Your instructions.

But Dhritarashtra had a different view. 

To him, Krishna was cunning.
He thought Arjun was ready to give up - ready to renounce the battle, but Krishna cunningly persuaded him to fight.

And Sanjay narrated the entire conversation between Krishn and Arjun - and all the teachings of the Gita to Dhritarashtra - but himself remained unmoved and unaffected.

Nothing touched him, nothing changed for him.

The same message.

The same words.
Yet, three entirely different outcomes.

For one, Krishna was the liberator.

For another, He was manipulative.
For the third, it made no difference at all. 

This shows that the understanding and usefulness of Gyana—knowledge—depends on the receiver. 

Its power does not lie in the words alone but in the heart and mind that receives it.

This is the true nature of Gyana—knowledge. 
How one receives Gyana is more important than the Gyana itself.
Its meaning and usefulness in life depend entirely on the listener’s or reciever’s perception.
