The mind must covert the senses into a lamp for removing the darkness which obstructs the knowledge of the Supreme Self. This knowledge which is gained by Yogins with the help of the especial instruments of Yoga, is acquired without any particular exertion by men who abstain from worldly objects.
प्रदीपार्थं मनः कुर्यादिन्द्रियैर्बुद्धिसत्तमैः। निश्चरद्भिर्यथायोगमुदासीनैर्यदृच्छया॥
