Crossing legs during davening

Q: Is there an issue crossing one’s legs during davening?
A: It is forbidden according to the Zohar but we do not make rulings based on the Zohar. The issue is that one needs to sit in "cherdat kodesh" - a trembling of holiness and it is certainly preferable not to sit with crossed legs. If a person must sit that way, it must be with the condition that it is modest, not prominent and not as if one is sitting on a sofa or in a cafe.
