Bhagavad Gita 2.25
The self is unseen, beyond thought and unchanging, so there is no reason to grieve.
अव्यक्तोऽयमचिन्त्योऽयमविकार्योऽयमुच्यते।
तस्मादेवं विदित्वैनं नानुशोचितुमर्हसि॥
avyakto 'yam acintyo 'yam avikāryo 'yam ucyate
tasmād evaṃ viditvainaṃ nānuśocitum arhasi
Translation
"This is said to be unseen, beyond the reach of thought, and not subject to alteration. Knowing it so, you have no reason to mourn."
Hindi
"इसे अव्यक्त, अचिन्त्य और विकाररहित कहा गया है। इसलिए इसे ऐसा जानकर तुम्हें शोक करना उचित नहीं है।"
Commentary
The self cannot be seen like an object or grasped by thought, so grief over its loss misses its target. Krishna draws the conclusion in a short sentence: knowing this, you should not mourn. The next verse, 2.26, is addressed to those who will not accept this teaching.
