Six Senses and Four elements

The six senses are arises from NamaRupa in PaticcaSamuppada. NamaRupa paccaya Salayathana. So basically all 6 senses are a combination of Mentality(Nama) and Form (Rupa - which is a combination of the four great elements). How is the mind (6th sense) created from the Form? As in from the 4 elements? Is it created from unseen molecular level 4 elements? Is it somewhat similar to Light? Where light was considered as an energy but later it was considered as both energy and particles as well?
