This proverb means that doing good, even to inanimate objects, will eventually benefit you. It teaches us that efforts and good deeds, even when they seem pointless, bring positive returns. A well-maintained wall can support you, just as a well-placed stone can serve as a seat. In other words, kindness and positive actions generate future benefits. Equivalent proverbs in English include ‘You reap what you sow’ or ‘Good things come to those who wait.’
