Turning within is called yoga.  Yoga is the divine discipline that gives a seeker the power to turn his attention within. It makes him understand the true purpose of the senses.  It uncovers the glory hidden within him.  It enables him to go deep into the cave of his own heart.   It shows him the way to unite heaven and earth. Yoga gives a seeker the strength to uplift his energies and become mature.”
