Crown of Treatises: Chapter on Mathematics

Nothing was beyond their knowledge. This is indeed correct. The connection of the Six VedangasThe six auxiliary disciplines of Vedic study: phonetics, ritual, grammar, etymology, meter, and astronomy. to the Veda is the primary means of its existence. However, it was not the intention of the ancient teachers to prove that all knowledge and science originated solely from the Veda; otherwise, the creation of countless texts on individual subjects would never have begun. In the present time, no further proof of this is required.

Apart from the Vedas, the independent ancient text of astronomy is famous by the name "Vedanga Jyotisha." For the performance of sacrifices and other rituals, it describes the TithiA lunar day in the Hindu calendar., the timing of festivals, and so on.

According to Somakara's writings, his commented astronomy text is considered to belong to the Yajurveda, and it is the work of Shesha. At its beginning is written, original: "Kalajnanam pravakshyami lagadhasya mahatmanah" "I shall proclaim the knowledge of time as taught by the high-souled Lagadha." From this, it is known that Lagadha had written some work on astronomy, and the present Jyotisha was written based on that original source. It appears that—just as the Panini grammar was created based on ancient Vedic grammar, and the Pingala manual of prosody was based on the foundations of Vedic meter—similarly, this Vedanga Jyotisha of the great soul Lagadha was composed upon the foundation of ancient Vedic astronomy.
