Bhagavad Gita · Chapter 15: The Supreme Person
Bhagavad Gita 15.10
उत्क्रामन्तं स्थितं वापि भुञ्जानं वा गुणान्वितम् ।
विमूढा नानुपश्यन्ति पश्यन्ति ज्ञानचक्षुषः ॥
utkrāmantaṃ sthitaṃ vāpi bhuñjānaṃ vā guṇānvitam | vimūḍhā nānupaśyanti paśyanti jñānacakṣuṣaḥ ||
The deluded do not see it as it departs, or as it stays, or as it experiences things, joined with the qualities of nature. Those who have the eye of knowledge see it.
Modern context
The soul is always there: arriving, staying, experiencing, departing. Yet the deluded never notice it. They see bodies, but not the life within them. Only those with 'the eye of knowledge' see it. This phrase appeared at the end of chapter 13. It is not a special physical eye but a way of looking that sees through the surface to what is living within.
