Another step in the preservation of Vedas was to prepare treatises known as अनुक्रमणिकाः || Anukramanis in which the names of ऋषि || Rishi, देवता || Devata, छन्दः || Chandas, similarly number of chandas, words are mentioned in reference to each hymn of the Vedas.

That these methods have been effective, is testified to by the preservation of the most ancient Indian religious text, the Rigveda, as redacted into a single text during the Brahmana period, without any variant readings within that school.

Understanding the way in which the vedas are organized into a definite pattern, gives us an insight as to how integral the learning system was and how it worked impeccably over such a long period of time. In addition to the veda pathapaddhati, knowledge in Vedangas are essential to understand the vedic language, meaning and their usage and the yajnas expounded in Vedas.
