According to Chapter 14, what is the transient nature of worldly existence and relationships, and how should one navigate it?

As described in Chapter 14, worldly existence is highly transient, likened to a flash of lightning in the clouds. Family relationships—mother, father, siblings, spouse, and children—are compared to pieces of wood floating in a river's current that meet for a moment before a wave scatters them, never to meet again. To navigate this, the chapter advises that while stepping into worldly affairs, one should be observant, as this allows spirituality to be attained without effort. Therefore, one should not be lazy in worldly duties or indifferent to human endeavor.
