The knot of adherence to dogmatic assertion of truth

What exactly is the "bodily knot of adherence to dogmatic assertion of truth" or "insistence that this is the only truth" in the sutta below? Why is it a bodily knot or tie? Please provide examples. The Pali term is "*idaṁsaccābhiniveso kāyagantha*". SN 45.174 translated by Ven. Bodhi: > “Bhikkhus, there are these four knots. What four? The bodily knot of > covetousness, the bodily knot of ill will, the bodily knot of > distorted grasp of rules and vows, **the bodily knot of adherence to > dogmatic assertion of truth**. These are the four knots. > > This Noble > Eightfold Path is to be developed for direct knowledge of these four > knots, for the full understanding of them, for their utter > destruction, for their abandoning.” SN 45.174 translated by Ven. Sujato: > “Mendicants, there are these four ties. What four? The personal ties > to covetousness, ill will, misapprehension of precepts and > observances, and t**he insistence that this is the only truth**. These are > the four ties. > > The noble eightfold path should be developed for the direct knowledge, > complete understanding, finishing, and giving up of these four ties.”
