This quote means that true love is usually quiet and peaceful, except in the very beginning when there is an act of true humility, which is a humbling of one’s self. True humility is when someone takes a step back and puts someone else first, often out of love, making an act of self-sacrifice. That is when true love is not quiescent. The phrase “nascent moments†means the initial stages of growth, so when genuine humility is at its very beginning, the peace and quiet of true love is interrupted.
