M4:70 — همچنین بر می‌شمر ای مرد کار / نسبت این از یکی کس تا هزار

This couplet serves as a direct instruction to the reader, summarizing the philosophical point Rumi has been building with a series of examples. The preceding verses establish that things like poison, candy, or the sea are not good or bad in themselves, but only in relation (nisbat) to a specific being. A snake's venom is life to the snake but death to a human; the ocean is a garden for a fish but a grave for a person on foot.

Here, Rumi universalizes this principle. He addresses the reader as a mard-e kār, a 'man of action' or a serious spiritual practitioner, and commands them to apply this understanding everywhere. The phrase "from one person up to a thousand" is a Persian idiom for 'in every single case, without exception.' The task is not merely to understand the concept of relativity intellectually but to actively 'count' or identify its workings in all of life's events and relationships. This is the 'work' the practitioner must do: to see beyond simplistic labels of 'good' and 'bad' and recognize the deeper, relative nature of reality.
