This is one of my favorite Shiva chants from Shankaracharya.

The lyrics (in Sanskrit with English translation) are included on YouTube.
I am not mind, nor intellect, nor ego,
nor the reflections of inner self (chitta).
I am not the five senses.
I am beyond that.
I am not the ether, nor the earth, nor the fire, nor the wind (the five elements). I am indeed, That eternal knowing and bliss,Shiva,love and pure consciousness.
etc. etc. etc.
