(Clearwisdom.net) Practitioners have embarked on the path of cultivation for various reasons. Some have come because they realized that Dafa's principles are true and correct, and others began cultivating because of sickness or fear of death. I was one of the latter, so I have some understanding of the mindset of these practitioners.
The Fa-rectification has reached its final moments and the old forces want to destroy practitioners who hold on to strong attachments and human notions. They know these practitioners care most about their health, and so the old forces are specifically using sickness karma to persecute them.
Through Fa study, I realized that whether one cultivates or not, they are restricted by the Fa principle, “What is owed must be paid for” (Zhuan Falun). As we have mistreated others in our past lives, we owe debts that must be repaid, and the ways of paying back these debts come in various forms. Everyday people do so through the troubles they experience in everyday life, including old age, sickness, and death. Practitioners should aspire to reach consummation so as to reward their creditors with benevolent resolutions. This is the best and most harmonious way to settle one's debts.
During the Fa-rectification period the old forces try to collect debts from practitioners, which interferes with the process of Fa-rectification, and can result in the loss of practitioners. We must clearly understand the Fa principles and dig out our selfish attachments, so that we can save sentient beings without interference.
The above is my personal understanding. Please kindly point out anything inappropriate.
