There's something profoundly universal about this phrase that transcends languages. When I first encountered this concept in Japanese literature, it struck me as a perfect encapsulation of moral introspection. The closest English equivalent might be 'Were my motives pure and free from self-interest?' but that feels clunky compared to the elegant conciseness of the original.
Western philosophy offers similar ideas - Kant's categorical imperative comes to mind, though it's more about universalizability than personal purity. The phrase makes me think of those moments when you replay a decision in your head, questioning whether you acted for the right reasons. It's that internal audit we all conduct, just put into remarkably precise words.
