Thousands of years ago, a great row of Aryans crossed over the Himalayas and, going toward the North of present India, established there their abode.
They were under the guide of the Manu Vaivasvata, a Solar Initiate of First Rank, and ten wise men called Rishis; their names are respectively: Marishi, Atri, Pulastya, Pulaka, Angryas, Kardama, Daksha, Vashishia, Bhrigu and Narada.
Aryans established all of their religions, philosophies, literature and arts upon Vedas.
Upanishads and Sutras become moral and philosophy of Hinduism, and are just vast commentaries of early texts based on their religion.
After fighting during 1,500 years, the Aryans that migrated to Central Asia handed down the Revelation and Tradition of a splendid Religion to their descendants; millenary Vedas conveyed this religion. Vedas, which means “pure science”, are a series of hymns and chants that those ancient people usually offered to their gods; in the beginning, they did not write down these hymns, but conveyed them orally from generation to generation.
Aryan established all their religions, philosophies, laws, letter and arts on Vedas.
The Upanishads and Sutras, which are moral and philosophy of Hinduism, are vast commentaries on early texts based on their religion.
Indian philosophy neither names nor refers to the absolute principle existing beyond any principle; the Buddha is the luminous exemplar of this modality in those ancient masters of India, for constantly he refused to speak of the beginning of the INFINITE.
