The kanji and the word are exactly the same. That means they share meanings as well.
When you have intention to do something, it feels like you're pointing at it with your heart. To say "heart pointing" in Japanese, you could say こころざし (心刺し). Guess what? The reading is the same thing as that, bringing it to こころざし. Now get out there and heart point to your dreams!
