Science has now agreed upon the point that most of its so called modern day "discoveries and inventions" are already referenced in the Vedas and Upanishads. E.g. being concept of atom, space technology & travel, nuclear warfare, just to name a few. Major Upanishads play a central role in developing this knowledge about truth on the nature of Atman and Brahmana. Minor Upanishads give an even more detailed insight about the same. Every knowledge that exists on earth, explored or not as yet, has already been detailed out by the Supreme God , in the apurusheya Vedic texts. These Upanishads serve as an easy mode of understanding this essential and existential truth as revealed by the Divinity to ancient Vedic Seers – who in turn conveyed it to their disciples and then to common man in an easy and understandable way.
It was always a scientific culture that understood the very mechanics and workings of this Universe. Their deities, their gods and goddesses were all a way of expressing and explaining these energies and their inter-working. Modern Quantum Mechanics is just starting to understand string theory, dark matter etc. which have all been fundamental to the Vedic understanding. Because of this, they developed ways and methods which allowed one to best tap into life-energy itself.
Vedic Culture, as it was practiced by the Himalayan Masters, was always a "way of life" and not a religion.
Their basic view was that, there is only ONE Supreme God-head (God as our creator) and each one of us can find our path to it- experience union with that divinity (Yoga) in their own way.
Because of this, anyone with any religious affiliations and beliefs can still benefit from their knowledgeable ways of Vedic Wisdom.
Our attempt here is to present this ancient wisdom in a modern light, so our readers can interpret the true, essential meaning more easily and then extrapolate it to their own specific scenarios and enhance the quality of their life and being-ness.
