I would like to know, in some detail as to how exactly the three types of Srutis were shown to portray the viSishTAdvaita view point.
Dear Shri sangom, Greetings!
I will try to give a synopsis of how Bhagavat Ramanuja reconciles the Bheda and Abheda shruti vakyas. I am given to understand that Advaitam says the bheda shruti are superseded by the Abheda shurti and therefore, only Abheda shrutis are valid. In the case of Dvaitees, I gather, they declare abhedha shruti don't even exist as it is a matter of how the words are split and so, Tatvamasi is really atatmvamasi, and so on.
The SVs claim that they are the only ones to do justice to Vedas as they don't reject bheda shruti as having been superseded and don't introduce extraneous syllables like "a" in front of Tatvamasi. This is what I understand and if I am open to corrections.
The way SVs reconcile Abheda and Bheda shrutis is mainly through the Antaryami Brahmana of Brihadaranyaka Upanishad, which Bhagavat Ramanuja calls ghaTaka (घटक) Shruti. These verses are supposed to connect the Abheda and Bheda verses. But before we get into that, the concept of what SVs call body/soul relationship must be explained.
Bhagavat Ramanuja in Sri Bhashyam explains that a a body/soul relationship exists between two entities using three concepts. These are referred to as ஆத்ம லக்ஷணம் and ச்ரீர லக்ஷணம்.
The three properties that constitute ஆத்ம லக்ஷணம் are dhaarakan, niyamakan, and seshi (supporter, master, and enjoyer) and the corresponding three ச்ரீர லக்ஷணம் are Adheyatvam, vidheyatvam, and seshatvam (supported, directed, and enjoyed). Bhagavat Ramanuja says, आधेय्त्व-विधेयत्व-शष्त्वानि शरीर लक्षणं. In other words, if these three corresponding qualities exist between two entities, then the one that is dhaarakan, niyamakan, and seshi (धारकन्, नियामकन् and शेषी) is Atma, and the one who is dhAryam, niyamyam, and seshan (धार्यं, नियांयं, शेषन्). What is unique to SV is, they claim this relationship need not exist only between cetanam and acetanam. If these three conditions hold between two cenatams, then one that is dhaarakan, niyamakan, and seshi is the soul and the one that is dhAryam, niyamyam, and seshan is body.
dhaarakan/dharyam refers to supporter and supported. Without the support of the supporter, the supported cannot exist. That is, in the case of living things, without the jeeva supporting it, the body cannot exist.
niyamyakan/niyamyam refers to controller and controlled. Jeeva controls the sarira. The body acts as willed by the jeeva.
seshi/sehan refers to the master and servant relationship. The body serves the soul, the body is the servant and the jeeva is the master.
SVs claim that this kind of three-fold relationship exists between Brahman on the one hand and jagat (jeeva + acetana) on the other.
One more concept that is relevant is the notion that while the body and soul exist together, due to limitation of language, references to the body often may seem like references to the soul and vice versa. For example when we say Rama is of blue complexion what we actually mean is Rama's body is blue is in complexion. The word Rama does not refer to the body itself, but it transcends the body and inheres in the Atman residing in that body.
Armed with these two concepts Bhagavat Ramanuja interprets the Antaryami Brahmana to mean jagat (jeeva + acetana) is body to Iswara, not like the body to a jeeva in a given birth, but one that is eternal, inseparable -- अपृदक्सिद्धि -- the reason this siddantam is called Visihta - advaitam.
Now, we get into Brihadâranyaka Upanishad III.7, where Brahman is described as, among other things, the body of earth,water,fire, air, sun, moon, stars, ether, light, speech, eye, ear, mind, skin, jeeva, intellect, matter, and he is the divine Lord Naryana, soul of all.
So, he is in-dweller of everything, cetanam and acetanam, and he is Iswara, who is Sriman Narayana.
Now, these Shruti vakhyas that connect the bheda shruti with abhetha shruti are the ones Bhagavat Ramanuja calls ghataka shruthi. So, when Shruti says Aham Brahmasi, it is like you and I saying I am Nara or I am sangom, the Nara and sangom do not refer to our individual body, but to the jeeva that ensouls the body in which we dwell. Similarly, Aham Brahmasi refers to the Parabrahman who ensolus our individual souls. Iswara is one who dwells inside all the jeevas as dhaarakan, niyamakan, and seshi. So, SVs say, interpreting Aham Brahmasi to mean each individual jeeva is Parabrahman is a gross misreading of the Shruti vakhyas. The jeeva is nothing more than mere dhAryam, niyamyam, and seshan to Sriman Narayana who is Parabrahmam, ensouling everything, cetana and acetana.
The case with tatvamasi is even simpler, it clearly indicates two entities, tat and tvam.
With this சரீரீ-சரீர relationship derived from the Antaryami Brahmana, both bheda and abheda shruti vakhyams neatly fall into place, at least for SVs.
Hope I made some sense, there is obviously lot more to this .....
with best regards ....
