THe 'anuvyAkhAna' is a work written by Srimadacharya,in response to the request by his beloved sishya,Trivikramapanditacharya. It is said that the Acharya dictated the four chapters of this work simultaneously to four of his sishyas.This work contains further explanation of the Bhashya for many 'sutras'. The implied meanings of several sutras would have been not clear or obscure, but for this work.While the language of the Bhashya is terse, this work is in simple style. In spite of it, it is necessary to study this work with its well-known commentary by Jayatirtha, 'SrimanNyayasudha' to understand it .

 ch.1: samanvayadhyaya-  The discussion of the first sutra 'aum athato brahma jignasa aum'  - the question why ,when and wherefore the study regarding 'brahma' should be undertaken itself has been dealt with in detail and the fallacy in the approach to the subject by other thinkers earlier to him has been brought out. Then,the fact that Narayana alone is referred to by the term 'brahma' and that He is represented by the letter 'aum'(having in it eight syllables) ,denoting the 'gunaparipurnhen thatva', 'nirdoshatva' and other qualities of 'brahman' has been established. The Acharya hasexlpained further that 'Narayana' can be understood by 'Agamas' alone and not by any logic. However,the statements of the Rishis and others like Dhruva,supports

the Greatness of the Lord.

 Ch2: avirodha adhyaya- It is in this chapter, that Srimadacharya has dealt with in detail all the systems of philosophy that had been in vouge at that time and showed that each of them were inconsistant with what is stated in the Vedas, brahmasutras,Bhagavadgita, and all authoritative shastraic works like the Bhagavatha.. He has also concluded in this chapter that there is hardly any difference between the Bouddha shastra and the Advaita except in the use of terms.

  Ch3: sadhana adhyaya- It is in this chapter Srimadacharya has stressed that bhakti combined with jnana and vairagya is the only path for attainment of Moksha. In fact Srimadacharya has said that one should first practice 'Vairagya' which leads to 'bhakti' which in turn leads to the desire for 'jnana'; once the path is laid the two,,jnana and bhakti go hand-in-hand to lead us in the path of attaining His grace, which alone can grant us the ultimate goal of reaching His abode.

Ch4: phala adhyaya-  In this chapter the concept of Moksha as in other

systems like Jaina,Bouddha etc. is discussed and the futility of their

concept of Moksha or liberation is established. The incongruency of the

concept of moksha in the Ramanuja system is also established. Finally the concept of Moksha as the one giving the Jiva ( a sattvic jiva) his intrinsic 'ananda' has been detailed,at the same time giving in detail the 'taratamya' amongst the gods in Moksha ,and as a corrollary the 'taratamya' among all jivas is established.

 A word regarding the famous commentary of Sri Jayatirtha, known as 'Sriman  Nyayasudha'  is a must in this context. But for this commentary, many details implied in the 'anuvyAkhyAna' would have been lost.  The well known work Parimala' by Raghavendra is his notes on this work. In this work Sri Gururaja says that he is able to read many many meanings into the 'nyAyasudha' but he has not given them all for fear of making the work very large. If this is the greatness of the commentary, the greatness of the original is anybody's guess.
