14. Importance of Ancient Knowledge
 Identity
 Culture: set of ideas, customs. To shape the
culture of society
 Received wisdom: provide path to transmit the
innovations to next generation
 Economic value: patent eg: pigeon pea

15. Defination IKS
 INDIAN: undivided Indian subcontients
- common culture, literary, social practice
- under single umbrella (eg. Chankya, Paninni)
 KNOWLEDGE: 2 aspects- gained by personal experiences
- by observations and analysis
 SYSTEM- a structured scheme to access the knowledge
(Granthas)
 vast repository of knowledge, needs to be arranged

16. The IKS Corpus- A classification
Framework
• Classification:
- important topic of
representative
knowledge corpus
-selective phrases
• Usefulness of it depends on:
Completeness, Compactness and Inter-
connectedness

17. IKS Corpus

 Challenges to understand- Method of representing
knowledge wsa very different
- ancient knowledge was oral
 Ancient western knowledge: readable
 Before 3000 BCE: dark ages; oral repository; Veda,
purana, Itihasas
 3000 BCE to 500 CE: recorded human history; much
contribution in different area was recorded
 500 CE to 1800 CE: strong foundations
Ref: table 1.1 (A sample of IKS repository)

27. Some Unique aspects of IKS

time to time
 Rsis are ‘seers’ (sant) of mantras not the authors.
 Vedas has well developed system of phonetics
recognized by UNESCO: Siksa
 Karma-kanda: Yajna
 Upasana-kanda: meditation

33. The four Vedas
 Traditionally, its Trayi Vidya (Atharvaveda
recognized later)

knowledge systematically to use it correctly for
society.
 To pass on the knowledge in future generation:
Paila-Rgveda
Vaisampayana- Yajurveda
Jaimini- Samaveda
Sumantu- Atharvaveda

34. The Rgveda

ritual work in a sacrifice like selection of land for
altar, offering oblations (Yagy) to sacred fire etc
 Yajna includes several topics: human anatomy,
metals, constelations, seasons, numbers,
geometry and yogic insight
 Two major branches:
 The krsna (black): more anncient
 Sukla (White): came later
 Yajnavalkya transferred his knowledge to 15

36. The Samaveda
 Word Sama—means to please, pacify or satisfy
 Singing of Rgveda mantras
