Eyes(2), Nose(2), Ears(2), Mouth(1), Anus(1), Genita (1) are the Navadwaram. Two more holes are there which already closed after the birth are TOP OF HEAD (new born baby can see it) & Navel (connected to the mother).First light of birth enters through head.
Who knows about keeping Navadwaram closed and keeping the soul within the universe (body/Prakruti) is called Siddha Yogi! They knows the secret of time and space! They knows the alchemy of creation in every element!
