In Chapter 28, Poem 4 of Attar's Mokhtar Nameh, the poet explores the metaphor of the 'knot' (گره) to represent the spiritual and emotional entanglements of the heart and soul. The initial tying of a knot and placing of a burden leads to an accumulation of 'many knots,' reflecting the compounding nature of spiritual struggles, attachments, or the complexities of the inner path. The speaker longs for this fundamental knot to be untied even once, suggesting that such a release would illuminate the entirety of their hidden state and spiritual condition.
