Saama Veda has 1000 Sections and the mantras are the same as in Rig Veda. All these hymns and mantras are set to music in it. Saama means "to bring `Shanthi' or `Peace' to the minds." The chanting of the Saama Veda really gives peace of mind and exhilarates the hearer. "Of the Vedas, I am Saama Veda" says Sri Krishna in Srimad Bhagavat Gita [10-22]. The main Samhitha of this Veda belongs to the Kauthama school, which is popular. There are also Ranayaniya and Jaiminiya schools in vogue, which show slight variations. The Samhitha is divided into two parts: Archika which are collection of Rik Hymns and Gaana which are songs. The scientific study of Indian Music has evolved basically from these Saama-Gaanas. Saama Veda has their own set of nine Brahmamnas and three Upanishads.

Atharva Veda has 50 Sakhas, and contains 598 hymns and 5038 verses. They are mantras in prose and as hymns, pertaining to Devathas not mentioned in the other three Vedas. It contains many mantras and many `magic formulas' designed to ward off evil and hardship and to destroy enemies. It also contains hymns about creation. They were brought to light by a Rishi named Atharvan. The word 'Atharvan' means fire priest. We have the Sounaka school of this Veda and small fragments of the Kashmirian version of Paippalada Samhitha. Arthasasthra and Ayurveda are considered to be offshoots of this Veda. It has Gopatha Brahmana and has Prasna, Mundaka and Mandukya Upanishads.

The four Vedas contain not only Philosophical and Theological verses, but also large segments of every aspect of mathematics and science. We can see astronomical calculations, Nuclear Physics, Space Technology, Biology and Chemistry and all Sciences of the past, present and the future. It is said that the Vedic trigonometry gives references by Saint Bhodayana who first gave the theory on right angle triangles. This was given to the Western world as theory of Pythogoras, which every High school student studies.
