The Upanishadas ace the Vedas that have been given the primary place of the Western-like scriptures in Hinduism. The Upanishadas informally complement the formal knowledge given in the Vedas. The Upanishads contain the knowledge revealed by the diverse ancient
gurus to fill in the gaps as the building blocks of what was eventually scripted into the Vedas. The Upnishadas precede the Vedas.
The Upnishadas are the words of the selfless gurus. The Vedas are the words of the disciples who wished to synthesize the knowledge so
that it may be shared formally beyond India for gaining prestige and reputation for themselves. Many of these disciples were the foreign
immigrants. Therefore, the Vedas have many Euro-centric ideas juxtaposed with the ideas mastered from the diverse gurus of India.
Vedas can be interpreted as the external body of the Upanishads that eventually attract one to the inner body that becomes luminous by
making the external body self-luminous in the minds of people.
