Sanatan literally means eternal. Dharma means something that is deserved. And Ved means knowledge.
So in essence, Vedic Sanatan Dharma refers to principles or a source of knowledge is eternal and unchanging. This knowledge is the source of four Vedas – Rik, Sama, Yajuh, and Atharva – is considered to exist since the dawn of humanity.

This knowledge permeates all branches of knowledge that we are aware of, and is considered the highest level of refinement that the human mind can aspire to achieve.
Veda is not religious books such as the Bible, the Koran or the Avesta. They contain no description of any ritual or belief-system that can bring us either Heaven or Hell. Instead, they contain intuitive pearls of wisdom that we all can relate to.
Veda does not require any faith as a prerequisite. Instead they only require an open mind and an attitude of wanting.
Vedas are not associated with any particular community, religion, race or culture. Veda reduced during the period when the whole of humanity is one race, one people, one culture and one nation. And therefore the message of the Vedas will be free of these limiting bias.
The significance of the Vedas came as the conclusion of this trip analysis, and not as the initial assumptions. It's like studying physics, in which formulas are derived from ground observations and we use the book to put things in the right order.
