Fellowship and love V enmity and hatred.

In fine, when traveling and journeying throughout the world, wherever one finds construction, it is the result of fellowship and love, while everything that is in ruin shows the effect of enmity and hatred. Notwithstanding this, the world of humanity has not become aware and has not awakened from the sleep of heedlessness.
Again it engages in differences, in disputes and wrangling, that it may set up ranks of war and may run to and fro in the arena of battle and strife.
