In India, it is customary that, out of respect, when a person's foot accidentally touches a book or any written material (considered to be a manifestations of Saraswati, the goddess of knowledge) or another person's leg, it will be followed by an apology in the form of a single hand gesture (Pranāma) with the right hand, where the offending person first touches the object with the finger tips and then the forehead and/or chest. This also counts for money, which is considered to be a manifestation of the goddess of wealth Lakshmi. Pranāma, or the touching of feet in Indian culture is a sign of respect. For instance, when a child is greeting his or her grandparent, they typically will touch their hands to their grandparents' feet. In Indian culture, it is believed that the feet are a source of power and love.
