I am nothing but Consciousness which is Everything

Who am I?
Whatever answer I give to this question will not be true till I say I am pure Consciousness and nothing else.

Consciousness is also termed as "Sachhidananda" which is combination of 'Sať   or truth , 'Chit' or knowledge and 'Ananda' or pure bliss.

If I say I am "my name", it is the name given to my body by my parents and it could have been anything and thus changeable. If I identify myself with my profession like doctor, engineer, manager etc then I am saying the work my body does and not what or who I am.

We were child some day and then we grew up to be adolescent,  then adult and so on. Throughout all these changes did "I" change? No the "I" or the seer of all these changes remained the same. This "I" is the only truth or 'sat' because it never changed.

This "I" is  also 'chit' or the knower of day and night , dream and awakening,  happiness and sorrow, life and death and everything else which can be seen or perceived by senses or imagined by our minds and the various states of mind itself. This 'I' can't be known because whatever is known is separate from the knower and 'I' is the knower.

When we establish ourselves in our true identity and see everything else as separate from us and transient, we experience 'Ananda' or pure bliss which is our true nature.
