Both are dependent upon each other and both manifest each other.
Social peace is, in a nutshell, the social law.
It is the law of each society that delineates acceptable and unacceptable behavior in society as well as punishment for unacceptable behavior or behavior outside the law. Without law, chaos would reign in society. And if chaos reigns in society, we will each become so concerned with survival that we will have little time to reflect on our spiritual nature. At the same time, spiritual peace drives social peace. The core of spiritual peace resides in the recognition that we are one with each other and one with God and what we do to anyone reverberates throughout all of humanity.
