«مِنْ عِرِفْ مَقَامُه ارْتَاحْ»

The saying holds that anyone who has an honest, realistic sense of their own abilities, worth, and limits is spared much inner turmoil. Its focus is self-awareness rather than formal social rank. Such a person does not chase what lies far beyond them, and so avoids the distress that follows.

The ease it promises comes from contentment rather than passivity or social suppression. Measured expectations protect a person from the repeated sting of disappointment, regret over lost chances, and resentment toward people who seem to have more.

Suitable when advising someone tormented by envy or by goals far beyond their reach, or when reflecting on one's own peace of mind. Said by a superior to someone of lower status, it could sound like a dismissive 'know your place,' so use it with care.
