Soulflame.

Some say each soul has but one match
That no other soul can burn alongside
Others say that many fit,
But be sure that it is a sacred ride.

To look within that other's heart
And see the flame shine bright and true
And to know its flaws yet still feel awe
Is to know that flame belongs with you.

Sometimes the very thing you're looking for is the one thing you can't see.
