A person becomes perfect (Siddh), when he or she perseveres and remains occupied in the action or practice a thing consistently. Perfection never attained by someone who does not practice. We need to understand that perfection or siddhi in Yoga does not arise by merely knowing the words, studying or reading the scriptures
