Verse
समदुःखसुखः स्वस्थः समलोष्टाश्मकांचनः ।तुल्यप्रियाप्रियो धीरस् तुल्यनिन्दात्मसंस्तुतिः ॥
samaduḥkhasukhaḥ svasthaḥ samaloṣṭāśmakāṃcanaḥtulyapriyāpriyo dhīras tulyanindātmasaṃstutiḥ
He who regards happiness and suffering alike, gold and mud and stone as of equal value, to whom the pleasant and the unpleasant, praise and blame, honour and insult, the faction of his friends and the faction of his enemies are equal things; who is steadfast in a wise imperturbable and immutable inner calm and quietude; who initiates no action (but leaves all works to be done by the gunas of Nature) – he is said to be above the gunas.
Gītā 14·24
