Bhagavad Gita 2.15
यं हि न व्यथयन्त्येते पुरुषं पुरुषर्षभ। समदुःखसुखं धीरं सोऽमृतत्वाय कल्पते॥
yaṃ hi na vyathayantyete puruṣaṃ puruṣarṣabha samaduḥkhasukhaṃ dhīraṃ so'mṛtatvāya kalpate
Meaning
The hero whose soul is unmoved by circumstances, who accepts pleasure and pain with equanimity, is only fit for immortality.
Understanding this verse
Simple meaning
Krishna says the person who isn't shaken by pleasure and pain, who stays steady through both, is ready for the highest freedom. Inner steadiness is a strength, not coldness.
In real life
A doctor in a busy emergency ward stays calm through both good news and bad, which lets her make clear decisions when it matters.
A young person who gets lots of likes one day and harsh comments the next learns not to let either define their mood.
Try this today: Notice one moment today where you're swept up by a high or a low. Take three slow breaths before reacting.
