AS THE UNBORNE CHILD -FETUS IS PROTECTED OR PRESERVED BY THE PREGNANT
MOTHER, THE FIRE IN THE 'ARANI' THE 2 WOODEN PIECES IS WORSHIOED BY MAN
WHO IS AWAKE AND WHO OFFERS OBLATION DAILY ,
AND THIS IS INDDED THAT ||8
Now in this Shlok the Lord of Death is telling Nachiket as to what is life or life principle. In ancient time the fire was created by rubbing the 2 pieces of weeds. This is taught to scouts in their survival techniques. So the fire is not obvious when we see the wood bot it generated by the wood and so it must be 'hidden' and protected .Just like the pregnant lady has a child in her womb. The mother takes care of the child and it is not obvious from outside about the fetus or wood. So we are told that we have the fire in ourself and we are not aware of it and when we realize the the fire within ourselves , we should take care of it and worship it . So this the independent force or image of the God.
We talk about the life or the SELF and we also talk about the PRANAS which are 5 in umber and which are the life forces and LEAVE the physical body upn the death of physical body. This so called fire is hidden and is inside and is well protected and those who are AWAKE will perceive it and then will need to worship it and then only one will KNOW about it. So the SELF is the Fire , Self is the PRANA and that is present in every living beings and that is that .
