Chandogya Upanishad 6.23Famous
intermediate
एवमेव खलु सोम्य विद्धीति होवाच जीवापेतं वाव किलेदं म्रियते न जीवो म्रियत इति। स य एषोऽणिमैतदात्म्यमिदं सर्वं तत्सत्यं स आत्मा तत्त्वमसि श्वेतकेतो इति॥
evameva khalu somya viddhīti hovāca jīvāpetaṃ vāva kiledaṃ mriyate na jīvo mriyata iti | sa ya eṣo\'ṇimaitadātmyamidaṃ sarvaṃ tatsatyaṃ sa ātmā tattvamasi śvetaketo iti ||
""Know this indeed, dear one: This body dies when the life departs; the life itself does not die. That subtle essence is the Self of all. That is the True. That is the Self. TAT TVAM ASI, Shvetaketu.""
What This Means:
The body dies, not the Self. The life-principle (jiva) never dies - only the body it inhabited. THAT YOU ARE.
Going Deeper:
The fundamental teaching of immortality: You are not the body. The Self is deathless. Tat Tvam Asi.
How To Apply This:
The body dies; you do not. Know yourself as the deathless Self, not the perishable body.
