Mbh 5.69.11

“Sanjaya said, ‘A man of uncontrolled mind can by no means know Janardana whose soul is under perfect command. The performance of sacrifices without controlling one’s senses is even no means to that end. Renunciation of the objects of our excited senses is due to spiritual light; both spiritual light and abstention from injury arise doubtless from true wisdom. Therefore, O king, resolve to subdue thy senses with all possible vigour; let not thy intellect deviate from true knowledge; and restrain thy heart from worldly temptations that surround it. Learned Brahmanas describe this subjugation of the senses to be true wisdom; and this wisdom is the path by which learned men proceed to their goal. O king, Kesava is not obtainable by men who have not subdued their senses. He that hath subdued his senses, desireth spiritual knowledge, awakened by the knowledge of scriptures and the pleasure of Yaga-absorption.’”
