"When the heart speaks, the mind finds it indecent to object" is actually a quote by Milan Kundera. This quote means that whenever we do something which our heart asks us to do keep more importance than that our mind asks us to do.
A wise man “Robert Bulwer” quoted that “A good heart is better than all the heads in the world”. Yes, definitely because most of our decision are taken by our heart. When we face a conflict, our mind may come up with numerous, different and quite logical reasons why you should act as it advices, but if you listen to and trust your heart. However, illogical and irrational ideas may be seem but they are usually right and you are happier as a result. Let me give you an example of mine that in beginning when I started to face audience my mind was stopping me saying that I can’t face the audience. What people will think of you? They will tease you. However, my heart was letting me go for it saying that I should go for it, I should not care what people think of me and at last I will succeed. And guess what? I listened to my heart, and today I am good speaker and I can face the audience very confidently. This is a very good example for you all readers to realize the listening heart is more important than listening to mind. I agree that at some point listing to mind is compulsory but heart is always at first preference.
Finally, I just want to say that what you can see by eyes doesn’t please you, then close your eyes and see from the heart. Because the heart can see beauty and love more than the eyes can ever wonder.
