There are few ways that a person can repay the debts they owe to their parents, who protected, carried and fed their child. Even should a person carry their parents on their own back, protecting and feeding them for as long or longer than their parents had done for them, this would be insufficient consideration: for a parent does much more than protect, carry and feed their child. To adequately repay the kindness of their parents, a person must become the same sort of friend any good parent is to their child. A child must ensure that their parent is comforted against doubt and the other fears of old age, that their history, obligations and traditions are conveyed, and that their mind and heart remain as nurtured as their body.
How, then, a person repays the debt to their parents speaks considerably to their character. Do they know that, despite whatever failings of their parents, they must repay this debt? Understanding that the debt must be repaid, do they know the proper way to repay their parents is not by heartless provision, but by whole-hearted loving friendship? Understanding the proper way to repay their parents, are they willing to perform the necessary sacrifices for their parents? Willing, are they able to? Able to, are they practiced in the performance, having learned the skills required through years of selfless service to the community or similar training? A person who fulfills all these is a likely person indeed, honorable and reliable, and may be counted to perform satisfactory service in whatever capacity that is required of them.
