This from the Guides upstairs.

Today’s lesson is on service to others. As we grow and mature spiritually we begin to align ourselves with service to others rather than service to ourselves. The accumulation of material things, the amassing of personal wealth or power, are a feeding of the ego state which hungers from a great emptiness. Yet that hunger cannot be satiated by external things. No amount of receiving can fill that void. That void can only be filled from within. It can only be filled by giving. By allowing the Light of God to shine through you and gifting it to others. As you share that love in your own personal way you naturally fill the void with the energy coming through you. Satiating that hunger or filling yourself from within is a byproduct of the giving. Such is the nature of love.
