To Indians, knowledge is sacred and divine. So it must be given respect at all times. Nowadays we separate subjects as sacred and secular. But in ancient India every subject - academic or spiritual - was considered divine and taught by the guru in the gurukula.
The custom of not stepping on educational tools is a frequent reminder of the high position accorded to knowledge in Indian culture. From an early age, this wisdom fosters in us a deep reverence for books and education. This is also the reason why we worship books, vehicles and instruments once a year on Saraswathi Pooja or Ayudha Pooja day, dedicated to the Goddess of Learning. In fact, each day before starting our studies, we pray:
O Goddess Saraswati, the giver of Boons and fulfiller of wishes,I prostrate to You before starting my studies. May you always fulfill me ?
