The Vedas are the oldest and voluminous sacred texts on Earth. They contain information about the structure of the cosmos and of all aspects of human life.
Once upon a time there was one unified civilization and a common source of knowledge – the Vedic, which was passed from generation to generation strictly unchanged.
According to the Vedas, time goes in cycles, and this is also an observed fact. Every day we see awakening in the morning (goodness), frantic activity in the afternoon (passion), gradual cessation of activity at night (ignorance), and tomorrow the cycle is repeated.
The same thing happens in the annual cycle: spring (awakening – goodness), summer (rapid flowering and fruit – passion), autumn and winter (wilting and complete destruction – ignorance). Then a new cycle comes. By the way, this is why it is more logical to celebrate New Year in the beginning of spring (which is done in most of the eastern countries) than in the middle of winter. The same cycle is repeated on a greater historical scale.
It is on the basis of the universal law of entropy the Vedas explain how the ages change in the direction of degradation. Like four seasons of the year, there are four ages – Yugas – which are constantly repeated.
Vast sections of the Vedas give a detailed description of all fields of knowledge, which people may require:
Town Planning – Vastushastra
Architecture – Sthapatyaveda
Grammar – Vyakarana-Vedangas
Mathematics – Shulba Sutra
Astronomy and astrology – Jyotisha-shastra
Chemistry – Rasayana Shastra
Medicine – Ayur-Veda
Martial arts – Dhanur-Veda
Politics and law – Manu Samhita
Civil laws – Niti-shastra
Etymology – Nirukta-Vedanga
Philosophy – the Upanishads, the Vedanta-sutra
And logic, sociology, psychology, history
But the most sacred part of the Vedas – is the sublime science of body, mind and soul – Divya-gyana.
