The meaning of the mahavakya tat tvam asi is to be understood by understanding the meaning of the entire sentence.
The sentence says jiva is ishvara, and ishvara is jiva.
Now vachyartha has to be understood.
Vachyartha for jiva is manifold. One is the owner of the body. People believe I am as good as the body.
But for shastra shraddhavaan, jiva is also sukshma sharira, that travels, and has body as its abode in current life only. So sukshma sharira can be said to be jiva, transmigrating body.
Now this can also be looked at as mind, and so on.
This is vachyartha or literal meaning.
Literal meaning of ishvara is manifold.
1. Cause of jagat
2. Jagat itself
3. Controller of jagat.
So abhinna nimitta upAdana karanam, karyam, and also the overlord, the one running the jagat with total shakti, bhagavan and so on. This is vachyartha. Again this is from shruti pramana. Only jagat etc. is from other pramanas. But manifestor, controller aspect is from shruti pramana.
So with respect to ishvara there is remoteness, and there is total difference in terms of shakti and pervasiveness.
Jiva has limited pervasiveness, has total dependence on ishvara and other jivas.
This is based on both experience and shruti pramana.
Now equation of oneness cannot be understood by understanding the sentence as considering the vachyartha.
So we have to apply jallajahal lakshana, and take lakshyartha.
So we take the two, and minus what is incidental , which is the attribute of savashaktiman etc. from ishvara, we also minus the remoteness. So we say I, is ishvara. So now remoteness is gone, but for I there is limitedness, dependence etc. That also we have to drop , and retain just I, which is non remote. But then ishvara will lose pervasiveness, so pervasiveness cannot be an attribute, so we have to apply all pervasiveness to I. So we retain just existence, consciousness and all pervasiveness alone as the lakshanas of self, which is non dual satyam, and then we can say that all else is mithya.
So here body mind is mithya, ishvaratvam is mithya, the individual body mind is mithya, the individual sankalpa is mithya, the mithya jagat has ishvari or shakti as the driving principle and the satyam jnanam anantam brahma is the non dual reality behind this .
So now the ahamkara totally applies to body mind complex and not to the self. Self is all pervasive asanga satyam, satchitananda rupam.
Body ahamkara etc is mithya. Ishvara who is the manifester of all that is , is also mithya, and as the self I pervade ishvara also. I pervade shakti also. I am the reality of shakti and shiva, I am the reality of all jivas, I am the reality of jagat. I look at myself as reality, and all that is here as reality. With name and form, I the reality, is available as various beings, as various things, as various responsibilities, as various orders, as the super order, the super mind, the supreme wisdom, as the srshti sthithi laya kArana, as the one reality. Entire srshti is I, srshti wisdom is I, mind is I, eyes ears are I, the I is the key, not the eyes or ears. In eye and ears, what is is I. In body , what is is I. In breath what is is I. In Smile , order that is is I. In breathing what is is I. In psychological order what is is I. In mind what is is I. Taste smell etc. what is is I. In heart organs etc. the order what is is I. In ahamkara, what is is I. In word and meaning, what is is I. In intellect what is is I. In memory hat is is I. In judegement what is is I.In desire what is is I. In confidence what is is I. In action what is is I. In result what is is I. In decider of result what is is I. In choice what is is I. In choicelessness, what is is I. In application of intellect, skill, in arts etc. what is is I. In courage resilience etc. in hard work etc. what is is I. In totality what is is I. In karma and karma phala, in any events and happenings, in unfolding o karma phala, in other people, in dependencies and interlinkages what is is I. In the overall order what is is I. In the given freedoms what is is I, In the dharma protection and protector, what is is I.
In totality what is is I. So like this nothing is left out, all that is is only purely and surely I. I is, and what is is I.
