Self Giving

What is the difference between self-givingness and helping?  Isn't the attitude behind both same -- given out of concern for other?

Highest Level in the Scales of Harmony mentions:

"Relationships at this level are characterized by ever-increasing joy of harmonious energies. Partners relate to each other through pure self-giving that expects nothing in return and knows there is greater joy in giving than in receiving. They recognize each other as the spiritual complement that fulfill and completes them. "
