Veda is a Sanskrit word, which means ‘knowledge’. ‘Vedic’ means ‘of the knowledge’, refers to the original knowledge given by God to humankind. It is the repository of knowledge on Spirituality, Mysteries of creation, Astronomy, Mathematics, Aeronautics, Geology, Agriculture, Ecology, Science and Technology. Veda Mantras are preserved intact in oral tradition since thousands of years by adopting a technique called ashta vikruti : eight variants like Jata, mala..etc. These variants of chanting were designed by rishis to protect the original text in pristine form.
