Bhagavad Gita 6.33 — Arjuna's doubt
अर्जुन उवाच। योऽयं योगस्त्वया प्रोक्तः साम्येन मधुसूदन। एतस्याहं न पश्यामि चञ्चलत्वात्स्थितिं स्थिराम् ॥
arjuna uvāca | yo'yaṃ yogastvayā proktaḥ sāmyena madhusūdana | etasyāhaṃ na paśyāmi cañcalatvātsthitiṃ sthirām ||
Meaning
Arjuna says: Krishna, this yoga of evenness you have taught — I don't see how it can last, because the mind is so restless.
