No one succeeds in perceiving how he enters into embodied creatures and how he goes out of them. According to the Sankhya mode, as also with the help of Yoga and the due observance of the ordinances prescribed by it, I am engaged in thinking of the cause of that Soul, but, alas, I am unable to comprehend that cause, excellent as it is. I shall, however, according to the extent of my knowledge describe to you that eternal Soul and his Oneness and supreme greatness. The learned speak of him as the one Soul. That one eternal Being deserves the appellation of the great Supreme Purusha.
नागतिर्न गतिस्तस्य ज्ञेया भूतेषु केनचित्। सांख्येन विधिना चैव योगेन च यथाक्रमम्॥ चिन्तयामि गतिं चास्य न गतिं वेधि चोत्तराम्। यथाज्ञानं तु वक्ष्यामि पुरुषं तु सनातनम्॥ तस्यैकत्वं महत्त्वं च स चैकः पुरुषः स्मृतः। महापुरुषशब्दं स बिभत्र्येकः सनातनः॥
