B.G 6.33
अर्जुन उवाच,
योयं योगस्त्वया प्रोक्तः साम्येन मधुसूदन। एतस्याहं न पश्यामि चञ्चलत्वात्स्थितिं स्थिराम् ॥३३॥
Arjuna said:
O Madhusudana, I cannot perceive the unwavering state of this Yoga of seeing equally (your presence everywhere) spoken by you, because of its restlessness.
Gīta Bhāshya 6.33
Restlessness refers to that of the mind. The importance of practice and dispassion in stabilizing the mind is highlighted by quoting Vyasayoga.
एतस्य योगस्य स्थिरां स्थितिं न पश्यामि। मनसः चश्चञ्चलत्वात्। उक्तं च -
Because of the restlessness of the mind, I do not see the firm steadiness of this yoga. It has been said —
"मनसश्चञ्चलत्वाद्धि स्थितिर्योगस्य वै स्थिरा। विनाभ्यासान्न शक्या स्याद्वैराग्याद्वा न संशयः॥"
"Due to the restlessness of the mind, the firm steadiness of yoga is not possible without practice and dispassion. Indeed, there is no doubt about it."
-इति व्यासयोगे ॥३३॥
- thus stated in Vyāsayoga.
