When Lord Kṛṣṇa delineates the yoga system to Arjuna, Arjuna says that the practice of this system is not possible for him.
- arjuna uvāca
- yo 'yaṁ yogas tvayā proktaḥ
- sāmyena madhusūdana
- etasyāhaṁ na paśyāmi
- cañcalatvāt sthitiṁ sthirām
"Arjuna said: O Madhusūdana, the system of yoga which You have summarized appears impractical and unendurable to me, for the mind is restless and unsteady." (BG 6.33)
