Whats the word?

What is the word?
    It explains our heart's feelings;
        Beckons to us
When we least expect it;
    Releases emotions
        Cooped up inside for ages;
Frames our every thought
    With fantasies and dreams.
        What is the word?
It is sometimes blind
    Hidden away for years;
        Makes us wallow
On someone else's every word;
    Strips us of our thoughts
        Of hatred and evil;
Shows us not only the light
    But the relief the dark can bring;
        Releases the passion
So longed for in our lives;
    Aspire to be
        The best we can be;
Become one
    With a soulmate.
        What is the word?
Oh, that's right;
    Love.
