I missed that one because I was writing my post while you were typing it. It takes me longer to write posts right now, I can't hold my arm in a typing position for more than a few moments at a time. I apologize for the sleight.
Kashmir is regarded as paradise as the original birth place of Aryan Hindus whose ancient homeland extended from Ganga-Yamuna rivers in the east to Araxes (Amu Darya) & Gomal rivers in west (Afghanistan). Kashmir upto Pamir (Mount Meru) in the north and confluence of River Saraswati and Arabian Sea in Gujarat formed the southern borders. From the ports of Gujarat commercial ships went around the world even during 3500 B.C, a few centuries before the ages of Ramayana and Mahabharata (3102 B.C) to Babylonia, Sumeria, Mesopotamia, etc. River Araxes is Arjikeya in Vedas, Kubha (Kabul) and Sveti (Swat valley in North Pakistan) rivers are regularly mentioned as western most extent of Aryandom. (Rig Veda - 10/75/5). Sea voyages for commerce clearly mentioned. (R. V - 1/116/3, 4/55/6, 7/88/3)
Kashmir was at the centre of this entire region. River Saraswati in its earliest form before changing course many a times and merging with Sutlej in West and Yamuna in East flowed from Indus in Kashmir to the Gujarat coasts via Punjab, Haryana and through Rajasthan forming the boundary of Mewar and Marwar regions. Northwest India to the west of Saraswati upto River Indus (also called Sushoma and Drishtavati for its prominent characteristics) was called Brahmavarta - the land of Aryan Rishis of Vedas, actually the original Aryan Hindu homeland. Kashmiri Hindu Pandits are the most pure and unmixed descendants of the ancient Aryans. They still have no caste divisions like the Vedic Aryans but later migrated throughout the world specially to the east in Aryavarta (North India) and to the west to Europe via Iran and Turkey (Hittite & Mittani Vedic Hindus) and Greece. Original Kashmiri Hindu migrants are hence also called Saraswats or people from Saraswati River bank. Like the Vedic people of Turkey (before advent of Turks & Islam) much of pagan Europe (before advent of Christianity) also followed corrupt form of Vedic Hinduism and their Gods. Hindus civilized Europe by making it their colony and gave them their languages like Iranian, born of Sanskrit like English, French, German, Greek, Latin, etc. Zend Avesta of Persians in actual Sanskrit spelling is 'Dhyan Abostha'!
So how does this state anything at all about the Hindu holy books? You clipped the first sentence in half from a text saying nothing about the Hindu Holybooks but rather giving a description of the pre 3500BC geopgraphy, then claimed it as proof that the Hindu holy books are wrong. This is completely and utterly fallacious.
edit: If you're conflating the Amu Darya with one of the Hindu Holybooks, it's the name of a river:
