According to Chapter 21, what is the relationship between different Saints, and what enables a person to meet them?

Chapter 21 explains that the company of Saints is not easily attained; it requires the dawn of good fortune and God’s grace. The author uses his own failure to visit Pir Maulana as an example, stating that 'one fears one's own shadow when ill-luck stands in the way.' Furthermore, Chapter 21 presents a significant spiritual concept: all Saints are 'essentially inseparable from one another.' Though they may take incarnations in different places and times for specific purposes, their signs are known to each other, and 'inwardly, they are all one.' This highlights a universal, interconnected consciousness among enlightened beings, suggesting their work and essence are unified despite appearing as separate individuals.
