Does the Hadith "Paradise lies at the feet of mothers" mean that kissing the ground beneath a mother's feet is kissing a part of Paradise?

The wording "Paradise is beneath the feet of mothers" is weak (da'if), but its meaning is sound, derived from another hadith: "Stay with her, for Paradise is at her feet." The meaning of this hadith is that obedience to and dutifulness towards one's mother are a cause for entering Paradise. And the phrase "at her feet" is an idiom signifying ultimate submission and humility, not literally kissing the ground.
