B.G 6.33
अर्जुन उवाच,
योयं योगस्त्वया प्रोक्तः साम्येन मधुसूदन। एतस्याहं न पश्यामि चञ्चलत्वात्स्थितिं स्थिराम् ॥३३॥
arjuna uvāca,
yoyaṁ yogastvayā proktaḥ sāmyena madhusūdana। etasyāhaṁ na paśyāmi cañcalatvātsthitiṁ sthirām ॥33॥
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.
Because of the restlessness of the mind, I do not see the firm steadiness of this yoga. It has been said —
"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."
- thus stated in Vyāsayoga.
