  My  Personal Definition:
  Pure in heart to me means to have good thoughts and good intents in our actions. And to be trying to improve every day, that is a like The Pure intent. That is what repentance is, and when we repent we become Pure. We become white in Him. Because Jesus Christ died and atoned and rose again for us, we can repent and be doing our Best everyday, and try to improve everyday, and we can be Pure! Its a wonderful plan. Its the Plan Of Happiness! If we are Pure, We are happy. And Its the true Kind of happiness. Not the fake kind. We get that joy when we think of improving everyday and keep taking advantage of the Atonement in our continuing journey of this life. :)
