In ancient India, Medical science were divided into two major traditions, the Atreya School based in Takshashila & the Dhanvantri School based in Benaras.
The Atreya school gave more prominence to the practice of medicine and their primary text was the Charaka Samahita while the Dhanvantri school gave greater prominence to surgery and referred to the Sushruta Samhita.
Now coming to sushruta, some scholars are saying that there was original Sushruta Samhita which had 5 books & 120 chapters. Later was redacted by Nagarjuna & some were added as supplements giving rise to 6 books & 186 chps.
The text in its current form contains details of around 1120 medical conditions, 700 medicinal plants, 400 surgeries and 121 surgical instruments!
Sushruta devoted his whole life to the pursuit of surgery proper. It was he who first classified all surgical operations into five different kinds & grouped them under heads such as
Aharya (extractions of solid bodies), Bhedya(excising), Chhedya(incising), Eshya(probing), Lekhya(scarifying), Sivya (suturing), Vedhya(punc-turing) and Visravaniya (evacuating fluids).
Sushruta emphasized on qualities of operating room too! He fumigated the room with vapours of white mustard, bdellium, nimva leaves, resinous gums of shala trees etc which foreshadows the antiseptic theory of modern times !
Now lets see some of the surgical operations he was excelled at,
RHINOPLASTY & OTHER PLASTIC SURGERIES - Sushruta was very famous in treating these cases. He was the first one who did precise and comprehensive Surgery on deformed nose & cleft ear lobes using skin grafts
LITHOTOMIC OPERATIONS - Sushruta was very well known in perineal incisions surgery as he did a number of Sx based on that, like removing stone from urethra etc !
He also did number of amputation on infected limbs& operating on abscess etc. Apart from that he also excelled in obstetrics part where he understood the mechanism of labour & operated it. He should also be credited for various eyes surgeries ( will discuss in detail separately )
He also taught his students how to operate on surgery by giving them practice through using plants such as pumpkin, cucumber, leather bag, bladder of dead animals for incision and sutures.
Apart from these, sushruta has written detailed analysis on how to treat fractures & dislocations, extraction of splinters, treating ulcer cases, hernia operations, cataract surgeries, limb operations, removing hemorrhoids & fistula etc !
Moreover sushruta was also interested in cosmogeny - study of origin and evolution of universe. He proposed the cosmic matter evolved from the unmanifested one, which again evolved into ahaṃkāra divided into 3 kind - vaikārika, taijasa and bhūtādi /tāmasa.
Dr. Frank McDowell, editor of the journal plastic and reconstructive surgery in his book " the source book of plastic surgery " described sushruta and his work as following,
Many of the advances in the sciences that we consider today to have been made in Europe were in fact made in India, some 2500 yrs ago. But unfortunately today's generation don't even acknowledge the great works done by our ancestors !
You are wrong..there r mentions of lord aiyappa in tamil literatures.The Tamil song, Shasta Varavu, states that there are 8 important incarnations and forms of Shasta. Among the Ashta-Shasta, the Adi Maha Sastha (Aiyanar) and Dharma Shasta (Ayyappan) are widely worshipped.
The iconography of Sastha is discussed in Agama texts such as Amsumadbhedaagama, Karanaagama and Suprabhedaagama. Sastha or Ayyappa was essentially a Tamil deity, according to H. Sarkar, who conducted one of the most comprehensive architectural surveys of Kerala temples.
This thread is mainly abt Manusmriti seen from a historians/indologist's perspective. Not for orthodox people !
Manava Dharmasastra (MDh) among the ancient Indian treatises on dharma was clearly established by the 5th century CE and possibly as early as the 3rd CE.
Many historians/indologist came to a conclusion that manusmriti was not composed by a single author as it was a gradual process at the hands of anonymous and successive compilers, editors, and copyists lasting for several centuries.
The Saṅgam age is the period in the history of ancient Tamil Nadu (the present Tamilnadu, Kerala, parts of Andhra Pradesh, parts of Karnataka and northern Sri Lanka) spanning from 4th C.B.C to 2nd C.A.D.
According to Tamil legends there were three Saṅgam periods, viz., Thalai Saṅgam, Iḍai Saṅgam and Kaḍai Saṅgam. However the historians refer to only the Third Saṅgam or Kaḍai Saṅgam as the “Saṅgam period.”
Most of the available Saṅgam Literature are from third Saṅgam period. This collection contains 2381 poems in Tamil composed by 473 poets, some 102 of whom remain anonymous. Now let's discuss briefly abt sangam literatures.
Amongst many allegations levelled by the critics against Savarkar, the following two are most prominent:
*Savarkar “apologised” to the British and then turned into a “British agent”
*Savarkar opposed the Quit India movement and helped British by recruiting hindus in army!
Savarkar favoured the militarisation of hindus even before WW2 occured ! And if he was a "British stooge" why did he write a letter to US prez to persuade UK to withdraw British imperialism?
Savarkar concluded that even though u openly resist Indian soldiers placement in British military, it doesn't gonna matter as u r already supporting them indirectly through taxes, working in postal, railways etc! So we should seize this opportunity!Even Netaji supported his view!
