The cities of the Harappan Culture had declined by 1500 B.C. Consequently, their economic and administrative system had slowly declined. Around this period, the speakers of Indo-Aryan language, Sanskrit, entered the north-west India from the Indo-Iranian region. Initially they would have come in small numbers through the passes in the northwestern mountains. Their initial settlements were in the valleys of the north-west and the plains of the Punjab. Later, they moved into Indo-Gangetic plains. As they were mainly a cattlekeeping people, they were mainly in search of pastures. By 6th century B.C., they occupied the whole of North India, which was referred to as Aryavarta. This period between 1500 B.C and 600 B.C may be divided into the Early Vedic Period or Rig Vedic Period (1500 B.C -1000 B.C) and the Later Vedic Period (1000B.C - 600 B.C).

Original Home of the Aryans

The original home of the Aryans is a debatable question and there are several views. Different scholars have identified different regions as the original home of the Aryans. They include the Arctic region, Germany, Central Asia and southern Russia. Bala Gangadhara Tilak argues that the Aryans came from the Arctic region on astronomical calculations. However, the theory of southern Russia appears to be more probable and widely accepted by historians. From there, the Aryans moved to different parts of Asia and Europe. They entered India in about 1500 B.C. and came to be known as Indo-Aryans. They spoke the Indo-Aryan language, Sanskrit.

Vedic Literature

The word ‘Veda’ is derived from the root ‘vid’, which means to know. In other words, the term ‘Veda’ signifies ‘superior knowledge’. The Vedic literature consists of the four Vedas – Rig, Yajur, Sama and Atharva. The Rig Veda is the earliest of the four Vedas and it consists of 1028 hymns.

The hymns were sung in praise of various gods. The Yajur Veda consists of various details of rules to be observed at the time of sacrifice. The Sama Veda is set to tune for the purpose of chanting during sacrifice. It is called the book of chants and the origins of Indian music are traced in it. The Atharva Veda contains details of rituals.

Besides the Vedas, there are other sacred works like the Brahmanas, the Upanishads, the Aranyakas and the epics Ramayana and Mahabharata. The Brahmanas are the treatises relating to prayer and sacrificial ceremony. The Upanishads are philosophical texts dealing with topic like the soul, the absolute, the origin of the world and the mysteries of nature. The Aranyakas are called forest books and they deal with mysticism, rites, rituals and sacrifices. The author of Ramayana was Valmiki and that of Mahabharata was Vedavyas.
