Hi! and Welcome... Hope you enjoy it!
It's a saying in our society that paradise lies beneath a mother's feet. We are reminded to honour and respect our mother because only with her forgiveness (through the imagery of kissing her feet) that we can enter heaven. Such is the level of honour given to mothers in our society. In view of this, I'd say:
"El cielo estα a los pies de mi madre"
If anybody has any other suggestion... you're welcome!
Regards,
