How can we think with heart while our mind is giving different message?

Don't think with your heart, feel it!

Don't feel with your mind, use it!

What the heart feels is true and out of goodness.
What the mind says may not leave you happy.
Follow your heart, and be contented!

From "The Little Prince"

"It is only with the heart that one can see rightly, what is essential is invisible to the eye"

Read this book and you will understand.

It is the way we view our roll models growing up. Roll models can really teach us very young different ideals, life rules, etc... and our hearts will sometimes not agree with what we "think" we know we've been taught. Roll models are not just parents. They can be peers or close family members such as aunts, uncles, cousins. Everyone grows differently. God created us all to be very special and not identical to the next when it comes to matters of the mind and soul. If it becomes a "dilemma", then you'll have a different question. :)

it's to double cross reference the information.

your heart is going bump-ity-bump-boom-bomm when your falling in love. your mind doubles checks it and makes sure you know what your doing and not just following emotion alone.

heart: oh wow, I'm in love.
head: woe buddy, you sure? i don't want to see you get hurt
heart: hell yeah i'm sure!
head: let me just check memory to see if you are feeling right?

process info in progress..... cool, system clear, go ask her out.

The mind is a very powerful thing and u have a lot of suppressed memories, stuff in your unconscious, things your not aware of, like fears, insecurities and other things that u might have seen, felt or experienced.
Your heart is merely just an organ. If u feel something with in your heart like love or some emotion...your head will automatically start giving u..lets call it the odds....the odds of it working and what ifs, it keeps thinking of all the possibilities. Thats why there is that saying follow your heart and forget about your head for a moment.

you should balance it...................

One is analyzing and playing safe, the other dares to win. Follow your heart..always

Living is about making decisions, small ones and big ones. If you do something out of love from your heart, you can't go wrong, regardless of what your mind tells you.

Tough one isn't it? Thinking with your heart can be hazardous sometimes. It is better to use the judgment of your mind than to follow your heart. They should both agree actually before you proceed. Good luck with that.
