Mostly , these are inherited from a system first enunciated in jyotish vedanga ( one of the six adjuncts to the vedas , 12th to 14th century bc ) , standardized in the surya siddhanta ( 3rd century ) and subsequently reformed by astronomers such as aryabhata ( 499 ) , varahamihira ( 6th century ) , and bhaskara ( 12th century ) 主要地，它们最初是由《周谛士吠陀》 （出于公元前12至14世纪，是吠陀六分支的其中之一）体系继承而来，在《苏雅西德汉塔》 （公元三世纪）里得以标准化，后来陆续被阿里亚巴塔（ 499 ） ，伐罗诃密希罗（六世纪） ，毗迦罗（十二世纪）等的天文学家革新。
There are others donating their possessions in charity as sacrifice ; performing austerities and penance as sacrifice , practicing the eightfold mystic yoga system as sacrifice and studying the vedas and aquiring transcendental knowledge as sacrifice ; all enlightened beings and performers of strict vows 还有其他的人把财物捐献给福利机构作为布施，把苦修苦行作为布施，把习练八种神秘瑜珈系统作为布施，把研习《呋陀经》以获得超然知识作为布施；所有被启迪了的人们，均奉行严格的誓言。
Thirdly , the extended work to build a complete system is modelling and verification , which can maximize the performance of the system . error check of the states conversion is also finished in this step . for that , iec61499 standard based net condition / event system ( nces ) models are developed which fit in with the veda rules 系统设计的后续工作是对系统进行建模和验证，看看该系统是否符合最优化条件，是否存在执行上的状态转换错误等等，并在iec61499标准的基础上，开发出一套适合于veda建模与验证工具的功能块网络条件事件系统( nces )模型。
