A butterfly, who had matured in a cocoon, even without having flight experience, bursts the cocoon and aspires to fly, for this flight instinct is embedded at the genetic level. Same with a man who while performing the Spiritual practices, following more the knowledge of the soul than the conscious experience of his life, does not wait for the cocoon to open on its own, but bursts this cocoon of matter by his own aspiration and by experience gained in spiritual practices.
