Question

exactly meaning of sometimes the heart sees what is invisible to the eye

Answer 1

Sometimes the heart sees the feeling or the pains of people but the eyes aren't able to see them
For instance, If u see a very small boy roaming on the streets without proper clothing and having many wounds on his body then your eyes won't be able to feel his pains but your heart maybe!

Answer 2

We are humans. We have feelings. Our emotions, feelings, love, affection, hatred, anger etc. resides in our heart. Sometimes when a person is in great dilemma or in extreme happiness he is not able to perceive things from his eyes, but his heart surely can understand his situation. We often say, ‘listen to your heart’ when someone is bewildered. This is because our heart can FEEL but our eyes can only OBSERVE. This is just like our eyes acting as a medium for our heart which is a doorway of solutions and endless feelings!
