Synergy in growth

In Paroh’s dream the seven fat cows grazed together at first. Why is that meaningful, why is it mentioned? Perhaps this means that the seven good years weren’t separate from each other; rather they fed on each other and strengthened each other synergisticly, so that the sum total was cumulative, much greater than just seven separate years of plenty. A sustained resurgence makes for a financial climate that begets great prosperity; in contrast to isolated pockets of good times. We must apply same for spiritual growth; one year of growth plus another does not add up to  two. It add up to much more. So take care to cultivate a continuum of growth!
