Example of one mystical experience.

Here’s one example of a typical report of a mystical experience, triggered by a disciplined meditation practice:

“I was enveloped in a love I could not put into words. This divine love was in everything and in me. At the core of my being, I was this love and so was everyone else. In this state of grace, there was no right or wrong, no good or bad, and no judgment whatsoever. Fear was non-existent. There was no death and I knew that we all live forever. Everyone I met was love. [...] I became aware that a presence other than what I usually think of as myself was looking through my eyes. I had become one with this infinite awareness that simply sees without judgement. It is the very essence of life, eternal life. I wanted nothing, nor did I needed anything.” - Retrieved from this link at the Near-Death Experience Research Foundation)

The correct answer is "Missouri was a slave state and would upset the balance between free and slave states."

Missouri’s request to join the Union increased sectionalism in that "Missouri was a slave state and would upset the balance between free and slave states."

Congress had to make a decision between sectionalism and permanent confrontations between slave and non-slave states. So the US Congress decided to accept Missouri as a slave state in 1840 but also accepted the state of Maine as a non-slave state to maintain the balance in Congress. This decision was better known as the "Missouri Compromise."
