Whereof Pascal Cannot be Translated

"Le coeur a ses raisons que la raison ne connait {pas / point}."
--Blaise Pascal

(ne...point is apparently an old-fashiondy version of ne...pas, I didn't find any mention of connotations other than that)

The heart has [its] reasons
{
 {which / that} reason [itself]
   {
      {cannot/does not/can't/is not equipped to}
      {understand/explain/recognize/comprehend/know [of]}
      /
      knows not [of]
   }
 /
 whereof reason knows nothing
}
