Looking at the two verses from Chhandogya Upanishad, discuss the nature of self; the true sacrifice.
The nature of the self
This self of mine within the heart, is smaller than paddy or barley or mustard or millet or the kernel of a seed of millet. This self of mine within the heart is greater than the earth, greater than the intermediate space, greater than heaven, greater than these worlds.
The true sacrifice.
This one (the wind) that blows, this is surely a sacrifice … While moving, it sanctifies all this; therefore it is indeed a sacrifice.
By looking at two verses we at find out what is meant by self and what true sacrifice is,
(i) As stated in the quote, it looks like self's has no ultimate size, it could be smaller as a millet, or barley and on the other hand it could be as big as earth, or space. Ont the other hand it could also mean that there is no such thing as self.
(ii) Here the idea of sacrifice seems to be connoted to action, a pious action which when done make other things pure by the action. Like the moving wind.
