Bhagwad Gita
Chapter 6, Verse 7
जितात्मनः प्रशान्तस्य परमात्मा समाहितः।
शीतोष्णसुखदुःखेषु तथा मानापमानयोः।।6.7।।
For one who has conquered the mind, the Supersoul is already reached, for he has attained tranquility. To such a man, happiness and distress, heat and cold, honor and dishonor are all the same.
