In the field of religions many important features of Harappan religion
were adopted in later Hinduism. The Harappans worshipped Pashupati Shiva in
his actual form as well as in the representative form as Linga, worship of
mother goddess, worship of trees, animals; serpents were all adopted by
Hinduism.
The Harappan civilization contributed towards the advancement of
Mathematics. The numerical and decimal system was evolved here which made
remarkable contributions towards Vedic mathematics.
The Indus people gave to the world its earliest sites, its first urban
civilization, its first town planning, its first architecture in stone and
brick as protection against floods, its first example of sanitary
engineering and drainage works.
Another remarkable contribution of the Harappan people was the
cultivation of cotton. Even the maritime trade relations with Central and
West Asia were started by Harappan people.
To them also belong the credits for producing some of the earliest
specimens of pottery. The Harappan way of making baked pottery, bricks,
beads, jewellery and textiles was adopted in the later civilization. They
also invented the device of a cart to harness the labour force of the
animals to the production of man's utility.
