This is a genuine quote from the Buddhist scriptures. It’s from the Mangala Sutta.
“To support mother and father, to cherish partner* and children, and to be engaged in peaceful occupation — this is the greatest blessing.”
*In the original it’s “wife,” rather than partner. The language has been changed to make it more inclusive.
“To support mother and father, & cherish partner & children—this is the greatest blessing.” Buddha
